> the gray area overlaps the text so that the changes are difficult to
When a web page uses layers or certain CSS definitions, it can happen that images overlap some other areas in the checked bookmark. This could be a side effect when WebSite-Watcher converts script based content into static content as the following screenshot shows.
To avoid that problem, you can select the option "Don't display images" in the bookmark properties. With that option, WebSite-Watcher shows a transparent image instead the real images or the gray replacements.
The option "Don't display images" was introduced in WebSite-Watcher 2017.
If you use WebSite-Watcher 2016 or prior, a solution might be to create a private plugin and remove all images from the HTML source code (this can be done in the event function "Wsw_PreProcessPage").
