User uploading files to my client's website

My client wants to collect images from ppl visiting his HTML website. The user simply needs to click a button, browse their computer, choose a photo file, and upload it to a folder on the server. Maybe a page that tells them that it successfully uploaded can appear after the transfer.

This can’t be that complex…but im a flash guy*, so please help me. I know how to make html forms, but only a little bit about php and that backend yee haw.

Thanks!

*i of coarse don’t mean to imply anything about flash designers…only myself :wink:
