Image size in Featured Product box

[CaroleAs]

It must be an easy fix but i noticed that the image in the featured product sidebox is larger than the box should be. I tried to change the image size from the admin panel but somehow, i guess i am not tweaking the right one because i never got anything to change.

Can someone direct me? Since i am VERY new to this type of coding, if it has anything to do with file editing, please, be precise for the poor old me! ;)

Thanks

Somehow, with all the tweaking, i guess i changed the right setting and it seems to work now.
