[ic] Image uploader breaks in 4.8.7 -> 5.2.0 upgrade

[Peter N.]

Greetings,

I just updated a catalog from a 4.8.7 installation to a 5.2.0. 
Everything works fine, except for image uploading.  When I attempt to 
upload an image, I get an error in the log saying:

host70.catalog.com huRhk5Jw:catalog.com - [08/July/2005:17:41:03 -0400] 
catalog /cgi-bin/catalog/admin/item_edit imgxyz.jpg is not a file.

I had similar problems under the 4.8.7 catalog, which I resolved by 
adding a symlink to my image directory called "images" in my catalog 
root.  The same symlink appears in the IC 5 version of the catalog, and 
everything else (server, servername, user, file permissions) are the 
same as with the 4.8.7 catalog, except file uploads don't work.

Any advice greatly appreciated.

Thanks,

Peter
