First: changing images programmatically makes it necessary for them to send individual images rather than one image to 30,000 recipients. That alone would slow them down. Second: If Razor can work for pure text (far easier to manipulate and create minor variations), then it should have the same capability for binaries. So your dismissal of razor is overly broad, and if taken to its logical conclusion would suggest razor is totally useless. -- _____________________________________ John Andersen
