Hello stm,

I see a few common mistakes here, and I think I can help you out.

First, any images you wish to display must to be saved on the SD card connected to your GTT. You can do this via the onboard USB connector by powering up with the unit in mass storage mode.

When saving your images, keep things simple and don't use any folders. Also, take note of the file names and sizes.

Next, to load an image, make sure you are in communication mode, then reference the image by name only, without the file path.

That should do it, but if you have any more trouble, please don't hesitate to post.

Thanks,
~Troy

Commands "Load Bitmap to Buffer" and "Display Bitmap" and also would work only with files of type "jpg", with files of "bmp" and "gif" the result isn't present.
