Yes, there is a 2MB size limit to the photos you can upload. If your photo is larger than 1600×1200 pixels, it will probably be too big. Internet resolution only requires a 1 megapixel photo or less to show it full screen. This limit is to conserve space for our 250 students on the blog.
Check to see what the filesize of your photo is (in Windows Explorer or Mac Finder). If it is greater than 2MB, then you will need to resize it. You should resize it to be no larger than 1024 pixels wide or tall.
