Dear Terry West,
When you use the default k2 module such as k2 content, you also see the jpg images now.
If you want to change the jpg to png, you can go to "modules/mod_sj_k2_slickslider/core/sjclass/components/k2.php", finding:
// image extract
if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'src'.DS.md5("Image".$item->id).'.jpg')) {
array_push($this->_images4[$item->id], 'media/k2/items/src/'.md5("Image".$item->id).'.jpg');
}
change to
// image extract
if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'src'.DS.md5("Image".$item->id).'.jpg')) {
array_push($this->_images4[$item->id], 'media/k2/items/src/'.md5("Image".$item->id).'.jpg');
}
if (JFile::exists(JPATH_SITE.DS.'media'.DS.'k2'.DS.'items'.DS.'src'.DS.md5("Image".$item->id).'.png')) {
array_push($this->_images4[$item->id], 'media/k2/items/src/'.md5("Image".$item->id).'.png');
}
Thanks
