Re: [APML] PS profiles; was: nice photoshop web site

Hey guys: How do I avoid including profiles in images? PS (6.0) never asks
me if I want to include or not include. According to the image info box at
the bottom of the screen (the one that normally gives the file size), my
current color setting is untagged RGB. Is this the color profile? I have
looked at the Color setting/Advanced dialog box and I don't see an option
for "automatically convert profile" or anything like that. I keep trying the
PS help index for this kind of information and it is much less than helpful.
Thanks,
Bert
