I use vBSEO myself, with the attachments in the file system, and it works perfectly well for me. Where the att are stored does not matter, as the mod is calling them via attachment.php which does all the routing. The popup does use the SEO'ed URLS for the images in my case, too, but it uses them just fine. There's also really nothing I can do, since I just drop in the standard URLs (attachment.php?attachmentid=XXXXX), and vBSEO exchanges them automatically. No way for me to interfere there if it does not do that correctly in your case.
