Here you can find a little VI which loads a Bitmap file into a picture control: http://ae.natinst.com/devzone/explprog.nsf/41ee12ddba6c766a8625684700691463/582e53e2c82a4dbe86256a8d006a4a82?OpenDocument
Very simple. 1) Put picture indicator on the FP. 2) Use "Read BMP" vi. 3) Use draw flattened pixmap vi. 4) Connect all outputs of "Read BMP" to all inputs "Draw flattened pixmap". 5) Connect output new picture of "Draw ..." to picture indicator.
