So far I always use 1024 px as the maximum horizontal dimension when incorporating images in a thread, e.g. 1024x683 px for a 3:2 image or 1024x768 px for a 4:3 image. However, I'd like to show some pictures in larger dimensions but that may not be convenient for people with smaller screens. I made up a poll to get feedback on this. The answers are based on 4:3 horizontal images, as a guideline the dimensions of a vertical pictures would be about 75 % of the horizontal dimension. So what do you think? Edit: poll removed, wasn't relevant.
