+ComfyUI-KikoTools provides carefully crafted, production-ready nodes under the "ComfyAssets" category.
+Each tool is built with clean interfaces, thorough testing, and optimized performance for SDXL and FLUX workflows.
+
+This project started out of frustration with keeping ComfyUI up to date and waiting for dozens of custom nodes to update—most of which I didn’t even use. After taking a hard look at my workflow, I realized I only needed one or two features from these nodes, many of which were abandoned or stuck in maintenance mode.
+
+I tried forking, patching, and submitting merge requests, but eventually decided to create my own curated collection of tools—fully supported and maintained by me. That’s how Kiko’s Tools was born.
+
+I’m sharing them here with the community, and I hope you find them as useful as I do.

+# Batch Prompts Node
+
+The **Batch Prompts** node loads and processes prompts from text files for batch generation workflows. It automatically cycles through prompts with each execution, making it perfect for testing multiple prompts in queue batches.
+
+## Features
+
+- **File-based prompt loading** - Load prompts from text files with `---` separators
+- **Auto-increment mode** - Automatically advance to the next prompt with each execution
+- **Positive/Negative splitting** - Automatically splits prompts at "Negative:" markers
+- **Persistent state** - Maintains position across ComfyUI restarts
+- **Wrap-around support** - Loop back to the first prompt after the last one
+- **Progress tracking** - Shows current position and total prompts
+
+## Input Parameters
+
+| Parameter | Type | Default | Description |
+|-----------|------|---------|-------------|
+| `prompt_file` | STRING | "prompts.txt" | Path to text file containing prompts |
+| `index` | INT | 0 | Manual prompt index (when auto_increment is off) |
+| `auto_increment` | BOOLEAN | True | Automatically advance to next prompt |
+| `wrap_around` | BOOLEAN | True | Loop back to start after last prompt |
+| `split_negative` | BOOLEAN | True | Split prompts at "Negative:" marker |
+| `reload_file` | BOOLEAN | False | Force reload file from disk |
+| `show_preview` | BOOLEAN | True | Show prompt preview in console |
+
+## Output Values
+
+| Output | Type | Description |
+|--------|------|-------------|
+| `positive` | STRING | The positive prompt text |
+| `negative` | STRING | The negative prompt text (if split) |
+| `full_prompt` | STRING | Complete prompt including negative |
+| `next_prompt` | STRING | Preview of the next prompt |
+| `current_index` | INT | Current prompt index (0-based) |
+| `total_prompts` | INT | Total number of prompts |
+| `batch_info` | STRING | Progress information string |
+
+## Prompt File Format
+
+Create a text file with prompts separated by `---` on its own line:
+
+```
+A beautiful sunset over the ocean
+Negative: blurry, dark, low quality
+---
+Mountain landscape with snow peaks
+Negative: foggy, unclear
+---
+Futuristic city at night
+Negative: old, vintage, sepia
+```
+
+## Usage Examples
+
+### Basic Queue Batch Processing
+
+1. Create a prompt file in your ComfyUI `input` folder
+2. Add the Batch Prompts node to your workflow
+3. Set `prompt_file` to your file name
+4. Enable `auto_increment` and `wrap_around`
+5. Connect `positive` to your text encoder
+6. Connect `negative` to your negative text encoder
+7. Set Queue Batch to desired number (e.g., 10)
+8. Run the queue - prompts will cycle automatically
+
+### Manual Index Control
+
+For manual control over which prompt to use:
+
+1. Set `auto_increment` to False
+2. Control the `index` parameter manually
+3. Use with other nodes that provide index values
+
+### Monitoring Progress
+
+The node provides several ways to track progress:
+
+- `batch_info` output shows "Prompt X of Y (Z% complete)"
+- Console logging shows current prompt preview (when `show_preview` is True)
+- `current_index` and `total_prompts` for custom progress displays
+
+## Tips
+
+- Place prompt files in the ComfyUI `input` folder for easy access
+- Use relative paths like "prompts.txt" for files in the input folder
+- Use absolute paths for files elsewhere on your system
+- The node maintains state across ComfyUI restarts
+- Set `reload_file` to True to force re-reading after editing the file
+- Empty sections (between `---` markers) are automatically skipped
+
+## Troubleshooting
+
+### Prompts not changing in queue batch
+- Ensure `auto_increment` is set to True
+- Check console for "[BatchPrompts] Auto-increment" messages
+- Restart ComfyUI after installing/updating the node
+
+### File not found errors
+- Check that the file exists in the ComfyUI `input` folder
+- Try using an absolute path to test
+- Ensure file has read permissions
+
+### State persistence
+- State is stored in your system's temp directory
+- Clear `/tmp/comfyui_batch_prompts/` to reset all counters
+- Use `reload_file` to reset counter for a specific file

+
+## Image Metadata
+
+When an image is selected, the node extracts and returns metadata including:
+- **Basic Info**: Filename, width, height, format, mode
+- **Embedded Parameters**: Generation parameters if present
+- **Workflow Data**: Embedded ComfyUI workflow if present
+- **Prompt Data**: Embedded prompt information if present
+
+## Examples
+
+### Loading an Image for Processing
+```
+Local Image Loader → Load Image → Image Processing Node
+                 ↓
+              [info] → Display Text (to show metadata)
+```
+
+### Setting Up a Multi-Media Workflow
+```
+Local Image Loader → [image] → Image Preview
+                 ↓
+           [video_path] → Video Player Node
+                 ↓
+           [audio_path] → Audio Player Node
+```
+
+## Tips and Best Practices
+
+1. **Save Frequently Used Paths**: Use the save button to bookmark directories you use often
+2. **Use Sorting**: Sort by date to find recent files quickly
+3. **Keyboard Navigation**: Press Enter in the path field to load a directory
+4. **Performance**: For directories with thousands of files, use pagination to navigate efficiently
+5. **Thumbnail Generation**: Thumbnails are generated on-demand and cached for performance
+
+## Differences from Original
+
+This version simplifies the original ComfyUI_Local_Image_Gallery by removing:
+- Tag filtering and management
+- Rating system
+- Global tag search
+- Metadata editing capabilities
+
+These features were removed to focus on the core functionality of browsing and selecting files, making the tool simpler and more straightforward to use.
+
+## Troubleshooting
+
+### Common Issues
+
+**Directory Not Loading**
+- Verify the path exists and you have read permissions
+- Check for special characters in the path
+- Try using absolute paths instead of relative ones
+
+**Thumbnails Not Showing**
+- Ensure the files are in supported formats
+- Check if the images are corrupted
+- Try refreshing the gallery
+
+**Large Directories Slow to Load**
+- Use sorting and pagination to manage large folders
+- Consider organizing files into subdirectories
+- Enable only the media types you need (images, videos, audio)
+
+## Technical Details
+
+The node creates a visual widget that runs in the ComfyUI interface and communicates with the backend through API endpoints to:
+- List directory contents
+- Generate thumbnails
+- Save user preferences
+- Handle file selection
+
+All file operations are performed server-side for security, with proper path validation to prevent directory traversal attacks.

+## Auto-Batching for Large Collections
+
+### Overview
+When testing large numbers of LoRAs (e.g., 75+ files), ComfyUI can experience UI disconnections or memory issues. Auto-batching solves this by automatically splitting your LoRA collection into smaller, manageable chunks.
+
+### How It Works
+1. **Enable Auto-Batching**: Set `auto_batch` to "enabled"
+2. **Set Batch Size**: Configure `batch_size` (default: 25, range: 5-100)
+3. **Select Batch**: Use `batch_index` to choose which batch to process
+
+### Example: Testing 75 LoRAs
+With 75 LoRAs and batch_size=25, the system creates 3 batches:
+- **Batch 0**: LoRAs 1-25 (set batch_index=0)
+- **Batch 1**: LoRAs 26-50 (set batch_index=1)
+- **Batch 2**: LoRAs 51-75 (set batch_index=2)
+
+Run your workflow 3 times, changing only the `batch_index` each time.
+
+### Visual Feedback
+When auto-batching is enabled, the `lora_list` output includes batch information:
+```
+=== Batch 1/3 (LoRAs 1-25) ===
+
+style-epoch-001
+style-epoch-002
+...
+```
+
+### Best Practices for Auto-Batching
+1. **Start with Default**: Use batch_size=25 for most scenarios
+2. **Adjust for Memory**: Decrease batch_size if you still experience issues
+3. **Combinatorial Mode**: Be extra careful - 25 LoRAs × 3 strengths = 75 combinations
+4. **Save Between Batches**: Save your results after each batch to avoid data loss
+5. **Use Plot Parameters**: The batch info appears in plot visualizations for easy tracking
+
