I would show you “my own report” as an example.
My previous project Visual Inspection in Katalon Studio - Reborn forcused on taking screenshots while navigating around pages of web sites, storing the images into files under a tailored file system, and compiling a report that shows screenshots with metadata.
The following URL shows an example of output report.
Please visit this and click around. You would see the page can show screenshot images rendered in a single HTML report. I suppose this demo page looks close to what you described above.
By a bit of twists, this report can present images in chronological order. I mean, the screenshots can be sorted by their timestamp. Also you can associate any metadata such as “comment” and “description” to each images, and all metadata of images will be rendered in the report.
The software works fine for me now. It took me several months to develop it. It was a tough task.
I published the source code of this project at GitHub. It is open-sourced. But I meant the program to be for my own use. I haven’t written enough documents yet; authoring documentations is much harder than developing codes for me. Therefore my project would be too difficult for you to reuse.
