Hi Antii, If you have a look at the stylesheets, where the images are scaled, you will see that only width is considered. As far as I know there is no solution out of the box. You can try to extend your stylesheet with logic to calculate the resize precentage of both scaling possibilities (in height and width) and finally base the decision on the result.
The problem is that you have to know the exact available height and width of the body. I tried this solution long time ago and it worked really good as long as the image wasn't embedded in some other elements, because the available width and height will change. If your images occure always in full body page width and height it should be straight forward.
