Can't upload a cover image for my campaign

If you see the image above you will see several blue bars above the upload screen. Those are all attempts to upload an image. Every time I try it fails and another blue bar appears.  I've tried every single troubleshooting check. The image is a JPG, it's under 5 mgb, I've disabled all extensions, I've cleared the data cache, and I've tried uploading it from a different device. It refuses to take. 

Hi David,  Which browser are you using?  Have you checked your storage capacity to make sure you have enough?  Have you tried reprocessing (opening and saving) the image in a different program than the one that created it?

I am using Firefox. The storage capacity may be an issue, but I'm uploading it directly from my computer so I didn't think that will be a factor. I have tried this.  I will try deleting some storage as my next step and report back. 

It was a storage issue. Deleting items from my library fixed the problem. I would have appreciate if I got some kind of error message telling me that. Because you can only see your storage inside the game it's not obvious that storage can be a factor outside the games. 

Hi David! You can check your storage settings by looking at your account page. It will tell you how much is consumed by graphics, and how much by audio. When deleting to make space, deleting audio files is usually a bigger factor, since the files are typically much larger.
