If you're using the Mobilia Theme, see this article instead.

We have seen some rare cases where images don't load (for example, your homepage banner).
This is because the theme is loading JQuery twice. This sounds technical, but is a very easy fix.

2. Use CTRL+F to do a 'find', and look for the word jquery.
