Help for Aimeos

Hi
We have the following problem:
The first image on a product is displayed too small on frontend (see attachment on top)
The image only is shown in the correct (bigger) size by mouse over. (see attachment below)
We want to have the images always in the bigger size (as shown when mouse over)
And mouse over shall show the image with a cast shadow.
What is the problem that the images are displayed small? How to solve?
Thanks

The default CSS styles assume that your images are in portrait format. Because your images are in landscape format, you have to change all relevant styles in the CSS (width and height or *image* rules).
