I'm testing things localy on my pc not on the host server and when I go
insert an imasge from the image folder it goes back 3 levels as so
<IMG SRC="../../../images/bevel_bg.jpg" BORDER="0" WIDTH="150" HEIGHT="40"
ALIGN="bottom" ALT="">
now al I want is to confige the alias to read any images from this folder on
my c:drive
is this correct if not can you give the correct configuration
images=c:\images\        http://127.0.0.1/c:/images/.gif/.jpg./.png
