One minute isn't practical. I'll have to let my boss know I need a Mac Pro then.
I also didn't know about Alt+Print Screen, that is super useful since I usually have to go in and crop the images afterwards to remove extraneous stuff.
And cheez, I shouldn't give you this advice since your penchant for grossly over the top statements, completely ridiculous made up numbers and absurd exaggerations are signs that I use to usually ignore you, but they make it hard for anyone to take you seriously, or actually, you know, listen to points that you may be trying (but failing miserably) to make.
And for the record, it takes my MacBook Air 2 seconds to open
this 108MB image. And then I can zoom in and out fluidly.
It takes my 2.4GHz Core i5 work laptop 2 seconds as well. So, not really sure where or why you are having problems. However, as soon as I try to zoom the image, it locks up for a few seconds, so fail for Windows there.
