Image Save

Displayed as Image Save, this is tbox's second image-export node, and it's shaped noticeably differently from its near-namesake ImagesSaver ("Image List Save"). Where that one takes a folder path plus a filename prefix plus an explicit format choice, this one is stripped down to just a path and a quality slider - no format field, no prefix field at all.

How it works

The cleanest read of that shape is that you supply the full destination yourself, extension included - something like path = "output/render.png" - and the format is whatever extension you wrote, rather than a separate dropdown choosing it for you. quality then only matters for whichever formats actually compress lossily; on something like PNG it's along for the ride and does nothing.

One honest gap worth flagging: the path field is multiline, and the schema doesn't spell out what that means for a batch of images. It could mean one path per line for a multi-image batch, or it could just be a wide text box for a single path. If you're saving more than one image through this node, it's worth testing on a small batch first to confirm it does what you expect rather than assuming - the pack's README doesn't cover this node at all.

The inputs and outputs that matter

• images (required IMAGE) - your image or batch.
• path (required STRING, multiline) - where it gets written, extension included.
• quality (required enum, default 100) - only bites on lossy output formats.

No outputs - this is a terminal save node.

How to install it

Via ComfyUI Manager: search ComfyUI-tbox, install, restart. Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/ai-shizuka/ComfyUI-tbox

then restart. Nothing extra to fetch - plain file writing, no model weights involved. The pack's README itself is essentially blank (three section headers, nothing under them), so for a node this simple you're not actually missing much by it having no documentation.

Common issues & troubleshooting

You wired this expecting a prefix or format dropdown and neither exists. You've likely got the two save nodes confused - this is the singular ImageSaver (path + quality only); the batch-with-prefix-and-format node is ImagesSaver, a different node with a near-identical name in the same pack.

Only one image out of a batch gets saved, or files overwrite each other. This is the untested edge case above - since the path contract for multiple images isn't documented, don't assume it "just works" on a big batch without checking a small one first.

quality seems to have no effect. Check your file extension - PNG and BMP are lossless, so the quality slider is inert on those; it only does something on a lossy target like JPG.

Canvas stops floating or scroll-zoom breaks after installing tbox. Unrelated to this node - it's a known conflict between one of tbox's own image-loading nodes and ComfyUI's frontend, tracked on the pack's GitHub issues and cross-referenced against a core ComfyUI issue. If it happens right after adding the pack, disable tbox's nodes a few at a time to isolate it.
