don't plot them in subplot, plot them in figure and save..

How to read multiple files is explained extensively in the documentation, on this forum, and in the wiki:

http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

etc

The first thing to decide is if you want to generate the file names, or if you want to read the names of existing files:

• generate names: use sprintf and fullfile.
• read names: use dir and fullfile.

You can also find some examples with my FEX submission natsortfiles:

And as KSSV has already said, simply use one figure and replace the image data on each loop iteration. Then saving is easy.
