I understand the concerns you have, Claude, but I would imagine that the concern is over how to have a "print-ready" image available online.
Yes, the end user can change the dpi before printing, as well as the dimensions of the image, but, when dealing with print shops for advertising, I've always had to send "print-ready", 300dpi images (if using .jpg files) if I didn't want the printer to make adjustments to the file to change print dimensions or dpi. It seems the same would be true if I were putting an image formatted for "high-quality" printing (300dpi) online for download and printing without making dimension or resolution adjustments. I haven't put anything online before to meet this requirement, but it seems as if delivering the file by email as an attachment or delivering as a download would be the same. Thoughts?

If it is for print quality reason, you need only be concerned with the total number of pixels. 1. you may very well have an image defined at "300 dpi", but if it is only 300 px wide, you will only get a one inch "good quality" printed image. 2. the resolution at which the user will print the image is his final decision anyway. 3. I know that the concept of so called "dots per inch" is embedded in image files, I don't know who the idea comes from, but it just does not make any sense : I agree that a virtual image does have dots, but where actually are the inches to make "dot/inch"? I other words, you may have a "75 dpi" image printed at a very good quality if it is actually 4000 pix wide, and a very poor "4000 dpi" printed image if it is only 75 pix wide. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:341827 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
