[ic] Bug in image listing widget

[Bob Puff at NLE]

I finally figured out why the image listing widgets were not working.

It seems that the code will not follow a symbolic link, even if the permissions are good.
(This is IC 5.2.0, Linux-Mandrake 9.2 box, ext3 fs.)  As someone else here pointed out,
if you go to the advanced tab of the widget and give the full path to the images directory,
it works.  However, if you give the path that IC normally uses, i.e., catalog root / images
(sym link), it fails.

This used to work in old IC 4.6.  Is there a fix, or a configuration error that is causing this?
