Hi,in a template, how can I show the original image, as opposed to a resized one?warm regardsRoland

Answering my own question (again). For this to work, you have to add the original image to the K2ModelItem.

In this file
/components/com_k2/models/item.php in line 103 (K2 v2.2) add this

$item->imageOrig='';

and after the other image declarations these lines:

if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'src'.DS.md5("Image".$item->id).'.jpg'))
$item->imageOrig = JURI::root().'media/k2/items/src/'.md5("Image".$item->id).'.jpg';

Now you can access the variable (and therefore the original image) inside any template by echoing

$this->item->imageOrig

I have no idea what implications this will have on stability, etc on your system and I only did preliminary testing. Maybe this could be added in K2, as sometimes people don't want scaling only regarding the width of an item.
