This is my first post here so please don't tear me apart if this has been asked/mentioned before (I couldn't find anything).

I just discovered the RingMe feature and was wondering if it was possible to add the hyperlinked button to my Gmail signature. I found a few things on Google about inserting the image, then attaching the link TO the image but those are older articles and Gmail must no longer allow that since it doesn't work for me. I understand you can embed it into a website but I'd like to include it into my Gmail signature.

Any help would be appreciated,

Thanks!
