Yeah I tried this option and hated it, I dont see why any great love for it remains?!? Perhaps it is because I run at a high(ish) screen res. that it doesnt bother me, but I finds that it tends to pull the old Photoshop trick and resize it to 66.6%, or in other words has reduced antialiasing (I know it does).
I say turn the evil option off, as a web designer of a few years standing, I and I would hope many would join in saying "view the pictures at fullsize as they were intended, if you have a small monitor my good design elements will have taken care of that, don't leave it to your browser to decide!!
