Suggestions for upload tool to embed on website?

Anyone know of a good upload tool I can add to my website for low-tech clients who need to send me photos? There will be enough traffic that doing this via email is out of the question. Most won't even know what FTP stands for, so that isn't an option either.

Ideally, I'd love for these to land on my server, but if it's necessary to push them elsewhere for me to download after the fact, that's acceptable (depending on price).

Just ran across UploadThingy and am wondering what else might be out there (or if I got lucky and hit the best option right out of the gate).

Thanks in advance for your opinions!
