Cesar - I am finding that the Getpicturevalfromhbitmap method call in your VFPPaint application has problems when the images selected for viewing are of a certain size. Selecting JPGs 900k+ in size results in the error shown below. Are you aware of a image size limitation?

XFCBITMAP.GETPICTUREVALFROMHBITMAP
