It's no problem being a beginner. Just be sure you
are doing your homework and realize everyone here is
*suppose* to be doing something productive with their
time besides answering questions. You really only have
to ask once. If someone knows the answer, or has time
to respond, they will.
In this case, I think we were giving you time to
discover for yourself what was wrong. When someone
jumps on the newsgroup like this, and starts asking
obvious questions, and seems in a big hurry for the
answer, there is a tendency to think we are doing
someone's homework assignment for them. We are not
here for that. But I think you will find we tolerate
all kinds of real questions cheerfully.
Cheers,
David

My problem is that I'm a starter in IDL language, so every little
thing is a big problem for me.
Thank you for your patient.
Aleksander.

I already got it. Thank you very much.

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
