Re: JPG File Size

Monitor resolutions have indeed increased.
If you have a 15" monitor, well, ok, it really is about 10.5 inches of 
horizontal display it would give you the following resolutions:

at 600 px ........ 57 px/in (dpi)
at 800 px ........ 76 px/in
at 1024 px ...... 97 px/in (this is the resolution that I use)
at 1200 px ...... 121 px/in
at 1600 px ...... 152 px/in

leastwise, that is what I have figured out.
