The attached patch explains the problem and offers a simple solution.
This is master-only, and it needs to go into 2.1. OK?

Subject: [PATCH] Fix View> LyXXHTML when math is generated as images. The
rewrite to the preview mechanism broke this, since the
images get deleted just as the file is being viewed.
Probably, a better solution would be to copy the images we know we
need, and somehow tell the main buffer about them, rather than leaving
all the generated previews lying around. But this works for now.
