Does it work if you use RGB instead of CMYK?
Turn off profile embedding. i also recommend you use RGB JPEGs, if this is meant for a preview image on some site that sells vector artwork.
damN!,.... jpegRGB...that old chestnut,
why yes I made that error 2 years ago and forgot! thanks guys, much appreciated I had to get this to the reicever as a quick preview,
very very pleased about some of the illustrator CS5 upgrades I viewed on the preview, love this program awesome, will post videos later of other additions I would like to see.
