Take a look at he following article, it lays some of the options out. They are all fairly good options.

If your users are happy with a bit of a delay, do it on the client (especially if you want to show them the results and ask if they are happy with it). If they are happier with a fire-and-forget scenario, offload it onto your server. As with everything, what meets the user's needs is the best way to do it! Gk.

The program locks up when generating the new JPGs, though, and I understand that has to do with the single-thread model in Flash. I've run across asynchronous encoders like the alchemy encoder <http://segfaultlabs.com/blog/post/asynchronous-jpeg-encoding> and the switchonthecode async encoder <http://www.switchonthecode.com/tutorials/flex-tutorial-an-asynchronous- jpeg-encoder> . Any suggestions on this? Also, I'll be uploading these different sized JPGs to a server. I guess a more basic question would be if the server (a typical LAMP setup) or the client (built in Flex+Air) is the better place to do this resizing? Thanks for your time! ~Gimli
