short_ribs was curious about ...

when you increase the ISO in camera that the small shot counter thingy
reduces how many shots you can hold on your memory card?

I had not noticed that effect -- and would not have expected it, either. 

In order to be sure about what is happening, you should take test shots
of a scene at various different ISO settings.  As you make those test shots,
nothing but the ISO should change: same scene, same lighting, same
camera position, ... .  Then repeat that sequence of tests with a different
scene, or two.  Take notes that indicate the image number and ISO value. 

After you copy the image files to your PC's HDD, see if there is a variation
in file size that relates to one of the ISO settings. 

That will tell you if the ISO setting actually influences the image file size. 

Check all of the camera's settings -- you may find that changing the ISO
also changed something else ... possibly something even more important.
