Hi, Can anybody tell me how to change in K2 image gallery size and layout photos, and how I can remove text back to top, thank you very much

Hi. The first step is to go to K2 parameters and set the image dimensions according to your needs. Note that changes will affect only the new images. The second step is to select the desired image size that you want to be displayed. Depending on context this option may be found at menu link settings, at module settings or at the category edit page. Regarding the back top top icon you can always create overrides ( details at getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates ) or just hide it using CSS :
