Setting cross origin on images using jrImage_display
Using Jamroom
all jrCore_image does is construct the url into a
<img src=........>
If you're making the src url
{jrCore_module_url module="jrEvent" assign="murl"}
{$jamroom_url}/{$murl}/image/event_image/{$params['item']['_item_id']}/original/poster.jpgTweak as necessary.
If it NEEDS to be addable in via a param im sure it could become an option.
