## Summary - When pressing `R` to refresh node definitions, image previews on LoadImage/LoadVideo nodes now update to reflect external file changes - Re-triggers the combo widget callback to regenerate preview URLs with a fresh cache-busting `&rand=` parameter - Extracts `isMediaUploadComboInput` from `uploadImage.ts` to `nodeDefSchema.ts` as a shared utility - Fixes #2082 https://github.com/user-attachments/assets/d18d69ae-6ecd-448d-8d7c-76b2c49fdea5 ## Test plan - [ ] Open a workflow with a LoadImage node and select an image - [ ] Edit and save the image externally (e.g. in an image editor) - [ ] Press `R` to refresh node definitions - [ ] Verify the preview updates to show the edited image
