In the latest version there is a small validation error generated for each album thumb:

Line 45, Column 90: No space between attributes.
…o/IMG_3663_100_cw85_ch85_thumb.jpg" width="100" height="100"alt="Mexico" />

The error is in the printAlbumThumbImage function on line 1461; it can be easily
corrected by placing a space before the alt attribute.

The same error is also present in the printImageThumb function on line 2617 - there is a space needed before "alt".

Would it be possible to correct these errors in the next bug fix release?

No problem. These will get fixed. But just a note. It is always best to create a ticket on Trac for any problems you find. That is the only means we have of tracking problems and insuring that they get fixed.

Ok, I created a ticket on Trac.
