Save/Load Picture

For quite a while I have been using MBS to write and open a custom file that simply writes out a series of array data and then a picture. Is there another way to save the photo in the file without MBS in the one file?

tout.writeline Playerpassword
tout.writeline username
tout.Write PictureToJPEGStringMBS(Myphoto,100)

I think I am stuck with MBS as there are too many user files that have it saved in that format to change the reading of old files
