Hello!
I'd like to replace the image of the article ... getting in its place the "Image Gallery" ...
The gallery would be on top and the text of the article below.
And also like to edit (delete) the name "Image Gallery" and "Click to open image!"

Is this possible?

Thanks

Then you will have to create a K2 override (read here how to do so getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates). Edit item.php file and move the gallery block of code right abover the item image code block.

Then you need to tweak the if/else statements eg:

if ( gallery)
show the gallery code
else:
use the image block here
endif
