change __item_icon__ for photos

Hi, where can i change the __item_icon__ outcome for photos and videos?

i want to change the path.
example www.site.com/m/photos/get_image/browse/image_1.jpg and change it
into: www.site.com/m/photos/get_image/original/image_1.jpg

is there some one here that knows how to do this....

What I would do is to leave the item_icon alone and create a new key based off of item_icon.  Then you can change the template for the particular area you wish to change.  To change the URL, all you have to do is to use the php string functions to find "browse" and change it to "original".
