Slash through Photos

Photos won't upload in gallery. They display with a slash through them, or a "draft" icon in the editing panel.

WHY!?!? 

Go to gallery. 

Hover over image until you see the sun looking icon above/far left. Click on that.

On the right, under Content, scroll down until you see Status and it will say draft in light grey. Click and you can change to published.

Did that work? I'm not an expert but I just had this problem and it was driving me nuts and I think I figured it out.
