Shelley, one good reason for zipping the files is so you can include a text file with the download that states clearly who the artist was (and possibly where it was obtained). If you allow just psds to be uploaded, then the person may not also be keeping track of where the file was obtained and who made the graphics in the first place. At least, that would be my main reason to not allow just psds - I think a text file should be included with the download.
