This post is from 4-years ago. It’s likely that pretty much all versions of RapidWeaver/Stacks and the stacks addons involved have changed since then.
I have no doubt that you’re seeing the same symptoms – but I suspect the fine details and root cause of the problem are different enough to merit a new forum thread.
I think posting a new forum thread with the details of your issue are probably a good way to go: most importantly include the stack involved. and since these problems (at least in the current thread) involve viewing images in specific browsers you should definitely include a link to published page. It doesn’t have to be the final page or the final webserver. A test page or test location is fine.
