Hello from Greece.
Please i want to help me with k2 multiimages plugin overriding. I want to override it with k2 standar template but i dont understand what exactly i must to do. Here is the Know issues from K2 multimages page:
"Template overriding
After install K2 Multiimages plugin, your standard K2 article template will be overrided with modified template of K2 Multiimages plugin. It is needed for providing new features.
You can override it in your template folder, just place yours templates\your_template\html\com_k2\default\item.php to templates\your_template\html\com_k2\item-multiimages.php
Then replace standard K2 image block in your template with modified block from plugins\system\k2multiimages\K2MultiImages\templates\item-multiimages.php, you can find it by "added K2Multiimage" text."
