(sorry the set doesn't even relate to the topic, haha.)
So, if you have a set or picture that you would like to save to your computer follow these easy steps:
*note: if it's just a picture you want to save you have to put it in a set*
Step 1: Make the set. Obviously.. aha. :/
Step 2: Publish the set. Again that is obvious ;)
Step 3: Get at least one person to like it.
Step 4: Click on the button the says '#.. of people like this'.
Step 5: You can then right click on the set and save it to your computer..
