I've defined the image_LRG of width=600 & height=400 and so I've modified the function popupWindow(url) in includes/modules/pages/product_info/jscript_main.php
With this values.
The problem is that the function open a window of width=610 & height=440 and so there are some white border (especially the height) that I don't like.
May be there is a problem in css(?) but in stylesheet_new.css I see the definition
#headerWrapper, #contentMainWrapper, #logoWrapper, #cartBoxListWrapper, #ezPageBoxList, #cartBoxListWrapper ul, #ezPageBoxList ul, #mainWrapper, #popupAdditionalImage, #popupImage {
margin: 0em;
padding: 0em;
}
What can I do? - Thanks
