My monitor is 2560x1440, everybody constantly goes out of their way to mention how huge it is. I can't even fit the first one.
Block was obviously being a cunt, but for real guys. For anyone who doesn't know, you can specify image size inside the image tags like so: [img width=XXX] ... [/img] or [img height=XXX] ... [/img]
I find that a width of 800 on most pics is about appropriate. For some things (like phone screenshots) that get really tall when they're that wide, you can use height=800.
