Files: Image Display

Hi when I was using the old version and browsed items the images I had attached to them appeared at the top of the page and large.
Now they appear further down the page under the heading 'files' and are just tumbnails.
Can I change this back to the way it was before?

Thanks for your help1

Different themes display files on the items/show page differently. Which theme are you using now, and which were you using before?
