Program for checking the pixel intensity of an image

I need to check the pixel intensity of an image and also be able to identify where on the image the higher pixel intensities are concentrated. I also want to be able to easily load whatever image I want into the program correctly without any hiccups or bugs. I tried various functions but I mostly get back a bar graph with the intensity levels shown in a graph but nothing else. I am a bit of a novice at this and would greatly appreciate the help. Thanks.

If you're new to image processing with Matlab, IA's tutorials are a great place to start (speaking from experience).

See some of my image processing tutorials. They all do that kind of stuff.
