Hey All,
I am new to javascript and currently coding a site with scripts that
are beyond my level of understanding. The problematic page has
thumbnail images that can be clicked on to zoom in. When clicked, the
preloaded larger image displays in a div layer that gets turned on. The
problem is that ie sometimes does not display the image - the
placeholder just stays blank. The script works fine in firefox and
netscape (haven't tried safari yet). Since I am new to this and this
only happens sporadically, I'm having a lot of trouble identifying the
error or a fix. Also, the src for the images is dynamically created
from the text name that displays below the bags. This is for content
management purposes. Any suggestions you can give would be much
appreciated.
Thanks,
Trent
