I've looked through the forums and can't seem to find the answer to my problem. Just done the latest install and when uploading an image, the thumbnail and image isn't showing, but the full image is.

Wondering if this is some small setting I need to adjust or something I'm missing, but it's been driving me mad for the past couple of days.

Any ideas would be appreciated. Thanks

Check the error logs about permissions. There is also a article on the user guide about what permissions. However, setup should have warned.

I have this same issue on two different sites I'm developing. I would be helpful if I know what I was looking for in the error log, or where to find the permissions in the User Guide.
