I would first complete your IDEA FitnessConnect profile to 100%.
Then use the “Create Profile Badge” link in the bottom left side of your page. Not only will this use the IDEA logo, but it will also display information about you (after all, you’re trying to promote YOU).
It will generate a preview of the badge and give you a box with the CSS code. You will have to enter this code in through the back-end of the website. So whoever did your website, you going to want to ask them to put this in for you. I happen to know how to do this because I designed my own website with a Joomla template and often make changes in the back-end of my website.
