Resolution-wise, you can take screenshots while playing in 1080p, but you will have to modify the image through cropping in order to submit your character with the proper image size.
Clarification needed: your example of 1440 x 900, neither number is between 1280 and 1024. 1440 as an individual number is still greater than 1280 and thus too large. Does that mean this is more about the total pixel number than the individual sides? Because as stated even in your reply, 1440x900 would not technically be in line with the rules and they would have to crop the shots same as a 1080p player.
