The test-poster just showed up — the one that I made from one of my blizzard photos upscaled a whole bunch.

I was worried, because I wasn’t able to make the picture as large as their templates say it needs to be [apparently, even though they want things to be 7000×4600 pixels at 200dpi, they don’t allow anything bigger than 4000 pixels — or so their stupid error says]. It looks okay, though, which means that I can start adding more photos as ‘large posters’ and not just framed prints.
