The photo you uploaded is too small! It must be at least 940 pixels wide and 180 pixels tall.

A lot of businesses are creating Google+ Pages. For those of you with little image editing knowledge, the Header image could be a stumbling block. If you're getting the 'The photo, you uploaded is too small! It must be at least 940 pixels wide and 180 pixels tall.' error, then the image you are trying to set for your cover is too small.

There are  free online image editing programs like http://pixlr.com/, http://www.online-image-editor.com/ or http://www.lunapic.com/editor/ you can use to resize your image. Chances are that if your image is too small, enlarging it will only make it blurry. Your best bet is to find a landscape image that's larger.

Here's a Google+ page cover template:
