Thanks for explaning me. Hmmm, in that case I don’t understand why resizing doesn’t work for me in Preference. I am really not able to enlarge the image as it always shrinks back when I drop the mouse. When I switch to a WP theme (Twenty someting) it works as it should. Any idea where the problem might be?
Do you mean adding this to the child theme CSS stylesheet? No, that did not help.
