Hi guys!
I run a site using Piwigo. I like Piwigo, but I really hate to create thumbnails and Piwigo also does not work fine for more than 50k images.
Well, since I do not understand any jscript and PHP, I've been a little troubled to do something very easy: To put a simple ad script!
I've also searched a lot but did not find anything to help me.
Please, where should I put my code? Here it is:

The only thing I need to do is to put this before . How should I do that?

Thank you all for caring!

By modifying the theme you are using. Probably just adding the script is not enough, somewhere probably the ad should be shown, right? So best start reading the theming tutorial:

The ad appers "flying" over the bottom. There is no need to put it the an specific place, the important is that the script is loaded and executed in the home
