I'm not completly sure I understand your scenario. If you are looking for a plugin which let you have tooltip with html, image, links, etc I would suggest tooltipster. Find docs and code here: http://iamceege.github.io/tooltipster/

I made a free WordPress plugin after reading augusto's recommendation for using Tooltipster.
