If you'd like to remove your collage you'll have to delete the HTML code. The HTML code is usually displayed in the "About Me" or "My Interests" section of your profile. What you need to do is go to "Edit Profile" and find one of the above categories. You'll recognize the HTML code for the collage because it has MyHeritage written in it somewhere. What is important, is to delete ALL the code related to MyHeritage, but not to delete code from other things you've added to your profile. What I suggest you do is to copy/paste the entire code of your profile to a word doc or similar before you start the procedure, and after the partial deletion of the collage code, go back and view your profile to make sure you got the right stuff removed. This way, if you've deleted something of importance you can copy/paste the entire code from your backup, back into your profile. This backup will also allow you to bring back your collage in case you change your mind later.
