How to insert custom jpg/png image into google maps polyline icon?

Question

JavaScript

Hello.
I have a picture in jpg/png, I want to insert it into a google map polyline.
The documentation says that custom icons can be added as path svg icons.
I tried to convert my pictures on some sites to svg , then opened them with a txt editor, copied from the path line (sometimes there are several lines with the path name), but it didn’t work :(
Please help me figure this out
