As you know there is a "validate and synchronize on screen image" command in eValid. It works by pending a "yes things are synchronized it is OK to go forward" question based on the checksum of an image -- actually, on the checksum of a portion of an image.
The tough point here is that if the image changes over time -- and you are trying to get synchronization based on some property of it -- then you may
never get the synchronization that you are expecting. Which, considering how eValid image sync works is not an unexpected outcome.
There are two suggestions here:
(1) Try to arrange the synchronization on a part of the image that you know (somehow) is NOT going to be changing?
(2) Change the image sync command to a "synchronize on document object property" for some other attribute of the element, or of the page/frame in which the image element is embedded. By doing the sync on some related property (attribute) of the page you may be able to achieve synchronization without having to be concerned that the image is non-constant.
