Riva raval, we posted you a lot of suggestions. You can convert the BitmapData instance of your image to JPEG or PNG using the classes of Tinic Uro. Theese output you a ByteArray which can be transferred to PHP using some technique I described on my blog.

All you have to do is building your PHP script from that point. You may want to have a look at mail(). You could do this also in Flash only but it saves much time to use PHP here.

Questions releated to PHP should be asked in another board and not this one. This post is only a summary of what mose people said here and it solves your problem. Feel free to ask any questions releated to theese topics.
