If you'll download the package from here again and replace your gallery_global.php file with the one in the package then that should take care of the orphaned images.

If the image being uploaded is smaller than the watermark then the watermark will not be applied. Otherwise you could end up with images that were nothing but the watermark.
and in one of the categories it doesn't count any images, despite there being some.
Try going to http://yoursite.com/forum/admincp/vba_gallery_admin.php?do=rebuildparents. Once you've done that, rebuild your category counters through the 'Maintenance' link under your vBa Gallery options and that should take care of the problem.
