To display JPEG from the USB while using GUIX, you'll have to create a GX_PIXELMAP struct for your JPEG data to instruct GUIX how to draw the image (if you add a JPEG to your GUIX Studio project and set it to raw, the generated resources c file will have a GX_PIXELMAP you can use for reference (I can post an example tomorrow). You can then use gx_canvas_pixelmap_draw to draw the image on the screen.
