[SOLVED] Category View not showing Images

I have a menu item linked to a blog category and this then lists the blogs and the text, but I don't see any images unless I open the actual blog. If I change the theme to another the images do appear in the category view, so it must be a setting in Atahualpa that I am missing.

I have searched the forum and found one thread with one reply that identified this same issue, then posted a reply saying they have sorted it, but not how!

Can anyone shed any light on this for me.

To see for yourself:

http://www.slimprogramme.co.uk home page is set to view blog entries and I have a TEST entry which does not show the image, click to read the blog entry in full and you see the image.

Many Thanks

Paul.
