Hi again, Lisa
Just noticed you're a fellow Kentuckian. Small world, eh? (I'm on the other side of the state from you)
I wanted to clarify a little on the file thing.
Someone you send a file to doesn't necessarily have to have the same programs you do, but they do have to have a program which will recognize the kind of file you send.
So, for example, if you're sending a music file like "coolsong.mp3", the recipient would have to have SOME program that will play MP3 music files (like WinAmp (most popular), MusicMatch (my favorite), or a ton of others).
The reason I mentioned it in response to your first post was that many drawing programs don't save files in standard formats (like jpg, bmp, gif) unless you specifically tell them to, and because of the size issue. A file that's only 40k in JPG format might easily be a megabyte or more in BMP format.
Hope that makes sense, and good luck!
