What is the purpose of る in the sentence?


I know the form ている, but is there any other form like just てる without an い
between ?

This is the sentence that I'm confused with : 写真の右に写って ** _る_**
小物が気になります。なんやろね？




It' a colloquial -ている.

Maybe my ears deceive me but I often hear younger children producing it in
that way. It's also how I formed it for quite some time when I first started
learning Japanese.
