Ungh. I'm sick of all this high-res bullshit. It's nice to have when there's a lot of small details in the work, but when it's just cell-shading? What's so special about it filling up FOUR screens instead of one? Not to mention, it usually makes the image look WORSE. -_-
No one's forcing you to view those vector traces and whatnot other HR images.
Get a browser that allows you to zoom, or resize the images yourself in PS if it bothers you so much - I'd gather the majority of people actually like their stuff being in a resolution that's halfway useful for anything.
I don't see what's so useful about a resolution that only lets you see an eyeball at a time on a 1024 x 768 screen. Rolo said it was for printing, but I don't see how it'd even fit on one page.
Well this shot in particular fits on an 8.5x12 page just fine at 300 dpi. Monitors are between 70 and 100 dpi, so of course it looks too big.
And Muey alluded to the other point of high resolution images, you can manipulate them further, rescale them, chop them up and whatever and they'll look better than if you did it to a 72 dpi one.
Why high resolution? It looks better. You just need a browser that will shrink the image for you to your screen resolution.
