JPEG image help - Easy for people who understand IDL?! [message #82299]

Hi,
I'm not really sure what this group is for but I'm hoping someone who understands IDL can see this and help me! Thanks in advance for reading on :)

So, I'm in "Intro to IDL" class, and understand mostly nothing.
We are given two files, one "ocean.jpg" and the other "sky.jpg". The question is to merge the two jpegs so one is on top, and the other on bottom, and to save this jpg.

Here is the procedure I have:

PRO jpghomework

file='sky.jpg'
read_JPEG,file,sky

file2='ocean.jpg'
read_JPEG,file2,ocean

tv,sky,true=1
tv,ocean,true=1

end

I have been trying to read and figure this out for two days, and it is due soon. Our professor is nonexistent (unreachable, no course material etc) so please think of this as I'm just a person who knows nothing about IDL, has Google, and the IDL workstation in front of me to try things out.

And, the homework question of course.

Thank you so much in advance! - Rebecca
