I guess there is an english barrier here because not one single person has understood the response I have made time and time again on this subject.
vbulletin uses image style buttons in every style they use that are different to match that each specific style.
Since our product integrates with many many forums and stylesheet colors etc it is impossible to do something the same as
vb who only code their product to match their own stylesheets. We do not code our application only for vbulletin here. We support 16 different integrations at last look.
This is not a hard concept to embrace here I find it hard that not one single person here understands this. I do not think it is a smart decision to replace that single link with some image button that is not going to match anyone's stylesheet. We would have way more complaints doing that than 3 users complaining they do not like the text link.
