I am making a buy and sell forum, am using some addons to make it better, i have manage to make the thumbnail bigger, but i cannot get the attached file picture to become bigger. if i put it on for example 500 px is does not get that big. See attachement for example. My question is; Is it possible to get it bigger with css\ add-on? and is it possible to not use the attached files manger but have pictures just bigger in the thread? without all the text around?
