which images is your store not showing? the images which you would expect to appear in the sub category grid (the box where possibly just now it says 'no image available') ? or did you add an image using the fckeditor?
okay, by default, you have three category templates to choose from, on the sample above, you have used products in lines 2
to change this, go to admin-->categories and select christenings
near the bottom of the page you will see Template: and a drop down list (which just now will say products in lines 2) from this drop down list you want to choose products in line 1 or products in grid click save and then view your storefront
