A useful bug report includes the page URL, browser name, operating system, file type, image dimensions, approximate file size, and the exact action that triggered the issue.
For model-assisted tools such as upscaling, mention whether the problem occurred while loading assets, processing the image, previewing the result, or downloading the file. For Collage Maker, include the number of photos and selected layout.
Screenshots of visible errors are helpful. If the issue depends on a private image, describe the image characteristics instead of sending the file unless it is necessary for troubleshooting.
