Sorry, seems I missed your last answer (I'm often only reading threads that appear on the front page).
The only possible cause for your problem that comes to mind would be that your datatype can't handle the picture(s), i.e. it is unable to decode 24bit pictures - try if Multiview is able to display the picture(s) (if it is, the the datatype works fine).
If that doesn't work, send me an e-mail with your project, I'll have a look at it.
