I was at http://www.lindsayimages.com/, and I liked the way that when you placed your mouse over a thumb, the background would change colors. I searched for how to do that on this forum, but I could not find it, and any help would be greatly appreciated.
All they did was add
style="cursor:hand" onmouseover="this.style.backgroundColor='#FFD542';"onmouseout="this.style.backgroundColor='#FFEFB5';"
to the <td> tag in the theme.php file. If you want just the thumbnails to be highlighted, just change the $template_album_list variable, in <!-- BEGIN album_cell -->...
<td align="center" height="100%" valign="middle" class="thumbnails">
If you want other changes, just go thru the theme.php file and change what you want.
