Breaking changes: - Single mode: Now uses file picker with direct browser-based image reading - Folder mode: Uses manual path input only - Renamed 'image' parameter to 'folder_path' for clarity - Added 'image_data' optional parameter for base64 image data Implementation: - JavaScript: FileReader API to read image as base64 - Python: Decode base64 and convert to tensor (no file system access needed) - Better UX: No confusing error messages about missing paths - Clear separation: File picker for single, text input for folder Benefits: - Single mode works without file system paths - No browser security issues - Cleaner user experience - Explicit mode separation
Random Image Picker - ComfyUI Custom Node
A ComfyUI custom node that provides flexible image loading with support for both single file and random folder selection.
Features
- Single Image Mode: Load a specific image file
- Folder Mode: Randomly select an image from a folder
- Subfolder Support: Option to include subfolders in the search
- Resolution Output: Automatically outputs image width and height
- Reproducible Random: Seed control for consistent random selection
- 🆕 Image Preview: Real-time preview of loaded images in the UI
- 🆕 File Browser: Convenient "Browse..." button for file/folder selection
Installation
-
Clone or download this repository to your ComfyUI custom nodes directory:
cd ComfyUI/custom_nodes git clone <repository-url> Comfyui-Random_Image_Picker -
Restart ComfyUI
-
The node will appear in the "image" category as "Random Image Picker"
Usage Tips
- Using the Browse Button: Click "Browse..." to open your system's file/folder selector
- Note: Due to browser security limitations, you may need to manually enter the full path
- Default Path: The input field defaults to your ComfyUI input directory
- Path Format: Use forward slashes
/or double backslashes\\on Windows - Preview: The loaded image automatically appears in the node's preview area

include_subfolders: OFF
seed: 0
Loads the specific image at D:/images/photo.png
Random Folder Mode
path: D:/images/
folder_mode: ON
include_subfolders: OFF
seed: 42
