 - `showcase_tempalte_v**.json`: A ComfyUI workflow designed to generate PNG images with embedded workflow metadata. The accompanying Python tool parses these images to extract the exact Prompt, generation parameters, and LoRA stacks, automatically compiling them into a structured `gallery.json` for the web gallery's "ComfyUI Showcase" viewer.
 
 - `filter_nsfw.py`: A script for rough NSFW filtering(based on NudeNet). It provides a quick initial screen, but manual review is still necessary for accurate results.

+- `batch_preview_generator/`: A batch pipeline for auto-generating and deploying preview images. It follows a structured 5-step workflow:
+  1. Uses `0_batch_template_*.json` to batch generate random preview images.
+  2. Runs `1_batch_regroup.py` to automatically reorganize all output images into their respective subfolders.
+  3. Runs `2_batch_process_meta.py` to extract the `meta` data from the `png` files and convert the images into `webp` format.
+  4. Runs `3_batch_upload_showcase.py` to batch upload the processed showcase folders to Hugging Face.
+  5. Runs `4_batch_modify_json.py` to automatically update the `models.json` data by regex-matching the `showcase` items for each entry, leaving you ready for a final manual upload.
