OK now that was easily understood.
I have a page where there is a img tag, & img value is stored in DB & using img tag it displays the img linking from DB, code used is->
<img src="snaps/thumbs/<?php echo($row_WADAuploads['Img']); ?>.jpg" alt="" name="Img" />
So when i apply show region it still shows the small img tag thing.. so how do we hide that when DB is empty in IMG FIELD. (database) please tell me how do we use show region?
