Convert CSS-Image-Gallery for eBay-use

Hi there, I found a CSS-Image-Gallery, that works on eBay. On eBay-Germany we are not allowed to use JavaScript. Thats why I want to use e Gallery in CSS. Well, I found this one (see attached), but this one needs to place Style-Tag in Site-header, which is also not allowed on eBay. Now, I want you to convert the Gallery in a way, wich works with INLINE-CSS, so no Style-Tag must exist. I have no Problem, if "hover" must be replaced with "active" or something like this, but Gallery must have: One Mainimage witch changes to selected Image and some Thumbnails to choose from by click, mouseover or something like this. Also a Link to an XXL-Image must exist, wich opens the XXL-Image in an new window ("_blank"). Project is urgent! First working sample will be choosen, if Price is ok.
