Display project information on picture

I want to display informations about project (project widget) over the picture when mouse is on it.
Informations like title and small expaination text like client widget but in transparent mode.
Is anyone have an idea to do it.

Dear Philippe,

Thank you for getting in touch here.

Unfortunately, Sydney doesn’t have such that feature yet. Sorry, I can’t provide you any custom code to accomplish it as it is a complex task; it goes beyond our support policy. If it is an urgent, I’d recommend you hire a coder on upwork.com or codeable.io.

Thank you for your understanding.
