use the filereference class and server-side scripting (like php).
Im a complete amatuer, I havent a clue what you just said :S, this is no offence to you, im a just a total noob at flash, sorry for inconvenience this may cause! But could you provide any more detail as to how uploading an image and then sending it to an email address could be done?
you'll need to find someone to do this for you or you'll need to advance your skill beyond beginner because this is an intermediate-level task.
you can start by using google to search for: flash <your actionscript version> upload file tutorial
then once you've mastered that, search for: <your server-side scripting language> email attachment tutorial
Thanks thats really helpful I will have a look and practice this.
