ComfyUI-LoadResizeImageWithFilenameV02

ComfyUI – Load & Resize Image + Filename

A lightweight ComfyUI custom node that extends the well-known KJNodes LoadAndResizeImage with an additional filename STRING output so you can feed the loaded file's name directly into downstream nodes (e.g. save nodes, text nodes, prompt builders).
