从URL列表加载图片

ComfyUI's built-in loader reads from disk. The moment your images live on a URL - a translation service's output, an OSS bucket, a CDN - you need something that downloads them mid-graph. That's this node: paste or wire a list of URLs, and it fetches each one into a proper IMAGE tensor your downstream nodes can use.

The mechanism is a plain HTTP fetch loop with a browser-ish User-Agent. It parses your urls input - which can be a JSON array (["a.jpg","b.jpg"]) or newline-separated lines; the input_format of auto tries JSON first and falls back to newlines. Each URL must be valid http(s) (it validates), must return a content-type starting with image/ (a PDF link gets skipped, not error), and gets a per-URL timeout. Loaded bytes are decoded with PIL, converted to RGB, and stacked into a batch.

Inputs and outputs that matter

• urls - required, multiline. The list to fetch.
• max_images - cap on how many to load, default 10 (1–50). Handy when a source gives you more than you want.
• timeout - per-request seconds, default 30 (5–300).
• input_format - auto / json_array / newline_separated.

Outputs:

• images - the downloaded images as a list of IMAGE.
• loaded_urls - JSON array of the URLs that actually succeeded. This is your audit trail, because...
• count - how many made it through. Watch this: failures are skipped, not fatal, so count is how you know the batch was thin.

The trap: silent placeholders

If nothing loads, this node does not raise - it returns a 64x64 black placeholder tensor and count = 0. In a big workflow that looks exactly like "the load succeeded but produced nothing." The console log is where the truth lives: every skip logs a reason (跳过非图片内容, download failures, invalid URLs). When a workflow comes back empty after this node, read the log before touching anything else.

Where it fits

This is the natural partner to the pack's API nodes. The translate flow ends with ImageTranslateResultExtractor handing you result_urls; those feed this node's urls input (it auto-detects the JSON array), and you're back to local tensors for preview/save. Same story for the signed public_urls out of AliCloudOSSUpload - though note those expire after an hour, so load them while they're fresh.

Installing

cd ComfyUI/custom_nodes
git clone https://github.com/jinchanz/ComfyUI-ADIC

Restart ComfyUI, or use ComfyUI Manager → "ComfyUI-ADIC". Needs only requests (already present). No models, no downloads beyond the images you point it at.
