Create a path from a placed png image with clear background
Hi, I'm learning Illustrator but still at a beginner level. I hope I'm using the right terminology in my question.
I've placed this png image of a tiger into my document:

The image has a clear background, the borders of which are the blue box around it. I want to isolate the tiger from the background and create a path from its silhouette. What is the quickest way to do this? It seems to be attached to the clear background and I have been unable to isolate it.
Thanks.
