I didn’t have this problem before but why it’s happening now is very strange. My blogs theme is Chateau. A few months ago I made some headers for my blog. They’re sized smaller than the size constraints of 960 × 260 pixels (940×198). The current one I have, I put in a few months ago and its fine. But when I try to change the banner which is the exact same size, the system wants crop it. Can someone tell me why this is happening?
