I've argued many times myself (as author of ImageCFC) that "DPI" is not a function of the image itself, but the meta-data of the image, as the DPI is *ONLY* used for print. So unless you're using Coldfusion to send a file to the printer after manipulating the "dpi", there's no point. that being said.. if you've got a jpeg that has the meta data for DPI, you could theoretically change the metadata to say that the image is 300 dpi, and when you open it in photoshop, it would be 300 dpi. But as was said, the DPI has nothing to do with the image itself, so if you've got an image with no meta data, you'd have to first convert it to a format that supported image metadata, add thei mage metadata and set the DPI. -- Rick Root Coldfusion/Flex Developer needed in Durham, full-time, no telecommuters.
