Question about sending recs

[Mndl]

Hi everyone, one of my dearest friends asked me if I could write a rec for the daughter of one of her good friends. I told her I'd be happy to do so, but I've never written a rec before and I want to make sure I do it correctly. I went on my sorority website and it seems that I can submit it electronically, but do I also have to send her picture, resume and transcript to the chapter? The PNM sent all of these things to me with an envelope addressed to the sorority. She's going to the University of Alabama, so really want to make sure I do it right. Thanks!
