I was wondering if anyone else had notice the small size of the image for 12-27, I'm showing
4 1/4" x 3 3/8". As compared to the usual 17"x13" on all the rest I've looked at.

The 12/27 source image has the same pixel dimension (1280 x 960 pixels for advantage members) as any other PSC source image
4.267 in x 3.2 in x 300 dpi = 1280 x 960 pixels

Perhaps you are more used to
17.778 x 13.333 x 72 dpi = 1280 x 960 pixels

For all internet-related practical purposes, the dpi number doesn't really matter, as your screen (when not playing with zoom in/zoom out) displays full size pixels (1 pixel on the screen = 1 pixel from the digital image).

The dpi (dots per inch) number only matters when you are printing.

12 - 27 inches...bloody hell don't you pass out from lack of blood...oh...lmao...sorry
12 -27 image...hah I got that wrong hey

I see vokaris is still going with the "it's not the size that matters" camp.
