Uploading pictures to web

[gregulator]

I am creating a website where users need to upload images that will get printed on large format items, roughly 6'x1'. Sure vector art would be great but most people don't use illustrator and the like. The interface is written in Flex (Actionscript 3.0). I am wondering what my options are for making the best looking prints possible while keeping the file size upload small. If users are uploading 100MB files they are going to be pissed they have to wait so long... especially if it crashes in the middle! Any suggestions? Thanks!

Unless you have full control over the web server you'll likely find that 100 megs far exceeds the maximum that the server is set to accept. Beyond that, I'm not sure that a discussion of how to get the best image quality out of smaller files fits the mission of the programming forum, but I'll leave it up for now. You might also try in the Digital and Video Cameras forum.

It really depends on the type of images you'll allow the users to upload. The best-case scenario would be black-and-white line art, though I doubt that's what you're after. For full-color, high-resolution, low compression images (which is what people probably want on a poster of that size), the file size will be big. There's not a whole lot you can do about it.
