It used to be that image urls surrounded solely by [ IMG ] tags were not clickable and that if you surrounded the [ IMG ] tags with [ URL= ], that the image was linked to that URL.

Recently, I noticed that an [ IMG ] tag creates an automatic link to the URL of the image, even if a [ URL ] tag is present (in which case that URL is ignored). For an example, look at my signature:

Code:
[ url=http://www.dvsmith.net ][ img ]http://www.dvsmith.net/cgi-bin/rand_sig.pl[ /img ][ /url ]
Just wondering what's changed, and if it can change back?
