Output Image Bridge

This one's easy to misread from the name alone. It's not the Output-category equivalent of RiceRoundImageBridgeNode in the sense of also returning an image - feed it an IMAGE, and what comes back out is a STRING, not a picture. That's consistent with every other node in RiceRound's Output category: whatever type goes in, the result is normalized to text, which fits a role as a debugging/log node rather than an image-processing step.

Why an image node that doesn't output an image

RiceRound's Output-category nodes exist, per the pack's README, purely to help you troubleshoot a workflow before you publish it - they're explicitly not meant to be part of the graph you actually run through RiceRound Publish. Read in that light, this node's job is plausibly to confirm that an image reached a given point in your graph and give you something inspectable about it (likely metadata or a status string, though the exact contents aren't documented) rather than to preview or forward the image itself. If you actually need to see the image while debugging, ComfyUI's own core preview node does that job better - this one is for confirming the data arrived, in a form consistent with how the rest of this pack's Output family behaves.

The input and output that matter

• images (required, IMAGE) - tooltip reads "only image," matching the same terse tooltip used on RiceRoundImageBridgeNode's input.
• Output: value (STRING) - text, not pixels. The node is marked is_output_node, so it's meant to terminate this branch rather than feed anything further downstream.

Installing it

Via ComfyUI Manager: search "RiceRound," install, restart. Or by hand:

cd ComfyUI/custom_nodes
git clone https://github.com/RiceRound/ComfyUI_RiceRound

then restart ComfyUI. No dependencies or model downloads are documented for this pack - it's a packaging and debugging layer, so install is light.

Common issues & troubleshooting

You wired this in expecting an image preview and got a string. That's the node working as designed, not a malfunction - every RiceRound Output node normalizes its result to text. For an actual visual preview during debugging, use ComfyUI's built-in Preview Image node instead; this one is for confirming an image reached this point, not for looking at it.

It's sitting in the workflow you're about to publish. Take it out. Per the README, Output-category nodes are for local troubleshooting only, and are explicitly not what belongs in the graph you feed into RiceRound Publish - if your published workflow needs to expose an image as a result, wire your image output straight to RiceRoundEncryptNode's images field instead.

You're not sure what the STRING actually contains. Neither is this article, honestly - the pack's README doesn't document individual node behavior beyond the schema, so the safest approach is to run it once locally with a known input and inspect the actual output rather than assume a specific format.
