Are you using the newer version of AutoGallery SQL
In edit your template, this should be on top in your template:
<%TEMPLATE
NAME Thumb
HTML <td><a href="##Gallery_URL##" target="_blank"><img src="##Thumbnail_URL##" border="0" alt="Thumb"></a></td>
%>
And this should be in your tables where you want to show your thumbs:
<%GALLERIES
HASTHUMB 1
TYPE Submitted
CATEGORY Mixed
AMOUNT 16
GETNEW True
ORDER Approve_Stamp
REORDER Build_Counter
HTML Thumb
INSERT
{
LOCATION +4
HTML </tr><tr>
}
%>
The above code should give you 4 thumbs in each row for a total of 16 thumbs and this code only works in the newer versions.
