I think you want to distinguish between the name of
an image file, which is what you have stored in your
arr_img array, and image data, which is something
entirely different. You will have to actually read
the image file to obtain the image data. Once you
have the data, the TV command will work a lot better. :-)

You will find the HELP command useful as you try
to debug your programs and understand the errors they
generate.

Cheers,

David
