sponsors block template

[atherdon]

1. move out part, related to sponsor logo image path.
   so instead of <img src="http://...." it will be <img src="{variable}"

a) it should be the same code, the same path, just separated
b) move this variable to the outside of your method
c) can we change the path? like use some image, like "placeholder kitten" URLS?

2. use image that located inside of your repo
   will it work or now - nobody knows.
   But you also can test it with hackernoon logo. as it will be always the same - we can grab it from the projects "assets" folder
