How to change size of pictures in only ONE category that I would like to use for book review. I watched k2 tutorial for book review and how to work with exta fields, but I can't set style when pictures goes on left, and extra fields goes on right..Now is situation that I have title, then go picture 100% width, after that is text, after that, at the end of the page is extra fields.

My pictures are 100% width, and they are above content. I use Gavick template (J! 3.3.6) and they told me to ask here.

I would like:
- pictures goes on left
- extra fields goes on right
- text goes bellow extra fields

Like on demo for book review.
Thank you very much for your time.

You can select a different image size in the category's settings. If the 100% sizes are hardcoded you need to address this issue to the template's developer.

As for rearranging elements, you need to create a new K2 template and move the blocks to the position you want. www.joomlaworks.net/blog/item/194-k2-inheritance-sub-templating This post will help you with the overriding.
