Is there any source of images which is supported by the SoloLearn?

Question

I noticed there are image samples here which is supported by SoloLearn just like the SoloLearn logo and a tree image where it has a URL of "www.sololearn.com/tree.jpg" Not sure about the URL. It's embedded on some lessons where it needs an image.
I want to know those sources and what are the other images supported here.
