Does it skip the same images every time you try it? Is there anything at all different about the ones that are left out (different icon or Open with… shown in the Finder, differences in extension e.g. .jpeg vs. .jpg, anything else) ? Do the missing images open okay in Photoshop if you just try to plain old open them?
Sorry, I hope that your bump gets better soon. How's Photoshop doing?
What's there to say? The feature is working fine here. there doesn't seem to be anything obviously related in the Adobe knowledge base, and none of the threads over at http://www.adobeforums.com/cgi-bin/webx/.ee6b362/ seem to touch on a problem like this (at least, the search doesn't seem to pick up anything that fits). It would be a good idea to start a thread there, since Adobe dev and support people do hang out there. You could also open a support case with Adobe if that option doesn't work.
