Hello Andy,

Thanks for the info. I do have both netpbm and ImageMagik installed on
my "test" server, so that is ok.
I can convert images, and them move them to my production web site.


Thanks again,

ewholz

(how come all the image stuff seems to come from the UK???, I guess no
one uses it in the US :)
