cd custom_nodes

Usage

Add an ImageRewardLoader node, this has the default model name prefilled, and is passed directly to the ImageReward loader. Note, the model will be downloaded on first run.

Add an ImageRewardScore node, connect the model, your image, and your prompt (either enter this directly, or right click the node and convert prompt to an input first). Connect the SCORE_FLOAT or SCORE_STRING output to an appropriate node.
