I am using the getCustomImage and printCustomAlbumThumbImage functions in my theme which seem to cause problems when trying to validate for XHTML.
The problem seems to be a result of the ampersand character being used in the URL.
Check it out here:

I replaced the ampersands lines 258-261 of classes.php for `function getCustomImage`, by the code `&`.
Everything seems to work great however this should be fixed in the next release...
