- Add support for new ComfyUI node types in gallery metadata extraction:
- CFGGuider for CFG scale values
- BasicScheduler for steps parameter
- KSamplerSelect for sampler selection
- RandomNoise/SeedHistory for seed values
- Update both main gallery (/gallery) and metadata viewer (/metadata.html)
- Fix metadata display issues where technical parameters showed as "Unknown"
- Add comprehensive test image and debug tools for validation
- Maintain backward compatibility with legacy KSampler nodes
This resolves metadata parsing issues with modern ComfyUI workflows
that use the newer node architecture for sampling and generation.
Fixes issue where PromptManager Gallery showed identical prompts for all
images when using workflows like Flux models that generate multiple images
with the same base workflow.
**Problem:**
- Gallery relied solely on PNG metadata extraction for prompt display
- Images generated from same workflow (e.g., Flux models) contained
identical workflow metadata but should show different prompts
- Navigation between images didn't update prompt information correctly
**Solution:**
1. **Enhanced metadata extraction:**
- Improved parseWorkflowData() to handle more ComfyUI node types
- Added support for PromptManagerText, UNETLoader, DualCLIPLoader
- Better negative prompt detection patterns
- Enhanced sampling parameter extraction
2. **New API endpoint:**
- Added GET /prompt_manager/images/prompt/{image_path}
- Queries database for actual prompt used during generation
- Provides accurate prompt data linked to specific images
3. **Hybrid metadata loading:**
- Primary: Query database for linked prompt data
- Fallback: Extract from PNG metadata if no database record
- Combines database prompts with PNG technical parameters
**Changes:**
- py/api.py: Added get_image_prompt() endpoint and route
- web/gallery.html: Enhanced loadImageMetadata() and parseWorkflowData()
**Result:**
- Gallery now displays correct, unique prompts for each image
- Prompt information updates properly when navigating between images
- Generation data refreshes correctly with prev/next navigation
- Maintains backward compatibility for images without database records
Resolves user-reported issue with Flux.1_Krea_Dev_workflow.json where
all images showed identical prompts in gallery view.
