text: whats is a bgheart.gif file and how would you open it? some one sent it to me in an instant message and i cant open it if you got it via email, don't open it!!! don't open it!!! don't open it!!!!!!!!!!!!!  otherwise, open it with internet explorer, firefox, netscape or a graphics editor.  a .gif suffix means "graphics interchange format".  it's most likely a picture.  but sometimes, viruses and worms are sent with this extension.  so be carefull!  don't click directly on it if you don't know what it is.  just drag and drop it into an open browser window.
