I am kind of new to all of this and I searched for a solution and couldn't find any, so I decided to post a thread about this.

Some themes don't have icons shown in the popup, I would like to know what I need to edit to be able too enable the icons in the popup.

Any help is very appreciated.

First of all you need to determine which popup modules the themes in question are using (it's either popup2.dll or xpopup.dll). Then you need to add one of these lines to the theme's config file(s):

(if popup2)

(if xpopup)

Keep in mind that if you turn icons on you might also have to adjust text margins and icon size/position, otherwise your popup might end up looking really funky. Take a peek in the popup2/xpopup docs for further info.

Thanks for the very good advice :)
Will try it at once!
