im trying to post an image and im copying the link on my picture address bar and it says invalid URL? what is the URL and if its the link to the picture why is it saying its invalid?

Universal Resource Locator. It's the web address where the item is located. Try right clicking the picture and copying the location. When you copy and paste the address up top, you are usually getting the page the picture is on and not the location of the actual picture.

For instance http://www.rcuniverse.com is a URL.

CGr.

Follow the steps in the schematic.

Actually its

Uniform Resource Locator

Just sayin
