If you move the images to /forum/images/ and change the image location value in the admin section to images/ all the images on the site work fine, but any smilies added to a post come up as dead images because of the following line
inc_func_posting.asp
this line
fString = replace(fString, "<img src=icon_smile_angry.gif border=0 align=middle>", "", 1, -1, 1)
should be
fString = replace(fString, "<img src=" & strImageURL & "icon_smile_angry.gif border=0 align=middle>", "", 1, -1, 1)
This applies to all the image replace strings
