Error message for images/logos that can't be uploaded?

[Rebecca Davey]

Hi,

Firstly, used JamTracker for the first time yesterday for a double header and it was fantastic, thank you.

One thing we stumbled on: trying to add a logo for the visitor team. It turned out that the image we were trying to upload was too big and after a resize it went fine, but before this whenever we tried to upload an image nothing would happen but there'd be no error messages etc so it was hard to figure out why isn't wasn't working.

Thanks,

Rebecca
