FELoadImageQQUrl

The name says "QQ" and the category says "remote," so your first guess is probably that this downloads images from Tencent's chat platform. The name is a lie - FELoadImageQQUrl just downloads an image from any HTTP URL and loads it into ComfyUI as an IMAGE (plus a MASK if the file has an alpha channel). No QQ account, no API key, no special service. If it's a URL and it returns bytes, this node will happily fetch it.

Why would you want that? Because ComfyUI's stock image loader only reads local files. Any workflow that starts from a web image - a reference you grabbed from a website, a face from a shared URL, a bot that pipes images in - needs something that pulls from a link. This is that something.

How it works

It takes three inputs, all strings:

• url - the image's address.
• file_type - the extension, default png. Used for the local cache filename, so .jpg, .webp, .png all work.
• file_unique - a cache key. If you leave it empty, the node generates a random one; the downloaded file lands in your ComfyUI input directory as <unique>.<type>. If a file with that name already exists, it's reused - so a fixed file_unique means "download once, then load from cache," which is a great way to keep a workflow reproducible across runs and avoid hammering a server.

Outputs: IMAGE (the pixels, normalized to 0–1) and MASK. The mask is derived from the alpha channel if present; otherwise you get an empty 64×64 zero mask - that's the "no alpha" sentinel, not a bug.

The two things to watch

First, it doesn't check content-type or do any real validation - if the URL 404s or returns garbage, you get whatever error PIL throws at open time. Don't point it at a page instead of an image file.

Second, and this is the important one: this node fetches arbitrary URLs from your machine. That's a security surface, same as any "load from URL" tool. Only wire it to URLs you trust. In a world where custom nodes are executed with full user-level access (see the ComfyUI_LLMVISION incident in the ecosystem write-ups), an image downloader that fetches whatever string you give it deserves a moment of caution before you paste an unknown link into it.

Install

Part of fexli-util-node-comfyui:

cd ComfyUI/custom_nodes
git clone https://github.com/fexli/fexli-util-node-comfyui
cd fexli-util-node-comfyui
pip install -r requirements.txt

Or via Manager (search fexli-util-node-comfyui), then restart. Light dependencies; config.yaml is only for the pack's API nodes.

Is it the most polished URL loader in the ecosystem? No. But for a quick "grab this link, keep it cached, move on" job it does exactly what it says, and the built-in cache key is a genuinely nice touch.
