Thank you Mike!
No I found it in Themes – Option – Lightbox Modal Windwo checked-box-it and voilà!

One more question: the pictures quality is not that good. I made a test and uploadet higher quality. but it is by far not as good as on my desktop. or when I post it on facebook.

Do you have any suggestions, how I can have a better quality?

Ok that is fine for me.

One more thing: I need to install 2 codes for my marketing into the “theme header stile” (not the google code). Do I also put that into the Quick CSS? Are there many different codes possible?

I have no idea about coding, that is why this might be a naiv question ;)

GREAT! That worked :)

Do you also have code, where i can choose a pictures or google calendar right under “Veranstalter”?
