Might sound like a stupid question but can I upload at uneven thousands of pixels, e.g. 1100 or 1300? I can see no reason why not but thought I would check as the common sizes seem to be even thousands, i.e. 1200, 1400, etc.
Reason I ask is because I like to use images as screen-savers and they fit my screen nicely at 1100. If I can upload them here at this size it will save me having to process two different sizes.
