Upload Files To Server using Flash

Can anyone please help me figure out how to upload files to a server using flash and if necessary php.

I am designing a site for a photographer friend, which has no ftp experience or anything. i would like to just have a page where she can upload her photos to the webserver herself.

I would like to do this via flash, if server side is needed, then flash + php.

Thanks much for any help. is there any tutorials about this?
