I just found out about ThingLink today. It’s a free/paid service to allow you to create links and other interactive elements on any image you can upload.
Check out this image I just created on ThingLink. Just place your cursor on the image and see it come alive with links.
Start by signing up for the Basic Business Plan, which is free. Upgrades are more expensive: $250 to $1,500 per month, but could be worth it to certain bloggers, book publishers, or author groups.
With the more expensive upgrades, you can remove the ThingLink tag and upload your own icons. With the $1,500 option you can also feature interactive icons in advertising banners.
