dynamic image display problem
Hi - the problem is more to do with preventing display of the "missing image" icon in the browser when there is no image in the db field. I have 2 pages - stockList.php and stockListDetail.php (code below) which allows for the possibility of up to 10 images to be stored in the db table. What's happening though is for a listing where there are only (say) 6 images, I'm then getting "missing image" icons showing on the page for images 7-10, which isn't what I want. Also these images are set to display as 100x100 px thumbnails, with a click-through from each to the full sized image. So what's happening with the missing images is that when clicked, the page reloads, which is also slightly annoying.
I assume that there's a way of setting this up so that if the db field is empty, nothing displays on the page - I've tried "show region if recordset is not empty" but that only seems to work on table rows, not cells...
Any ideas?
thanks in advance,
Jeff
