加载图像(带文件名) / Load Image With Name

Load Image With Name is what you get when someone takes ComfyUI's stock Load Image node and asks "but what if I need to know which image I loaded?" It behaves exactly like the native node - same input directory picker, same drag-and-drop upload - with one extra output: the filename, without the extension, as a string.

That tiny addition unlocks a genuinely useful pattern. Batch processing where each output file should keep the name of its input, so a folder of cat_01.jpg, cat_02.jpg, ... comes out as cat_01_processed.png, cat_02_processed.png instead of a pile of ComfyUI_00001_... names. Or feeding the filename into a prompt, a save path, or a caption so downstream nodes know what they're working with. If you've ever built a loop that processes twenty images and had to manually map outputs back to inputs, you know exactly why this exists.

How it works

The implementation is a close copy of ComfyUI's own loader, so everything you're used to carries over: it lists files from folder_paths.get_input_directory(), supports upload, and the MASK output is the image's alpha channel - same convention as the native node. The filename is pulled from the path with the extension stripped: upload test_image.png and filename outputs test_image.

The inputs/outputs that matter:

• image - dropdown from your input directory (or upload button).
• Outputs: IMAGE (the pixels), MASK (alpha channel, in ComfyUI's standard form), and filename (base name, no extension).

One subtlety: because the filename is computed from the actual path at execution time, it stays correct even in batch contexts where the dropdown selection is being driven programmatically. The node also hashes the file for change detection, so replacing an image on disk with a same-named file properly re-triggers the graph instead of serving a stale cache.

Installing it

Part of the RUI-Nodes pack ("Rui-Node🐶"), a bilingual Chinese/English node collection. Install the pack once via ComfyUI Manager (search "RUI-Nodes") or by hand:

cd ComfyUI/custom_nodes
git clone https://github.com/rui40000/RUI-Nodes
cd RUI-Nodes
pip install -r requirements.txt

Then restart ComfyUI. Base requirements are just torch, numpy, Pillow, and requests - nothing extra for this node.

Where people get burned

Almost nowhere, which is the nice thing about a faithful clone. The only thing to keep straight: the filename output is the base name without extension, so if you're building a save path, remember to re-append your output extension yourself. And as with any input-folder loader, images you upload land in the same shared directory all your other loads use - fine in practice, just don't expect per-workflow sandboxing.

If you need to load from an arbitrary absolute path instead of the input directory, the same pack's Load Image By Path is the sibling for that job.
