circle – marker image

Hello , Sorry for my english . I am wondering whether it is possible to add a certain point marker icon on my choice. Please suggest possible methods . I watched the library version 2.0.2 jvectormap there is a function but did not find it in the version that is used in the plugin . At least while trying to make a crutch , but so far not very successful. Will be glad to answer any . thanks for listening.
