How to make your own YouTube background?

How do you make it to where if you have just pictures not colors on your background image on youtube?

• Okay...on my youtube account I have blue as my background but now I want multiple pictures on it.I did that but it still shows the themes and colors and it bearly shows my picture It just has my picture in certain places. How do I delete my themes and colors? I just want the multiple pictures.

• Answer:

  From what you have said I guess that there is only one picture in as your background. So try this: go on your channel and find where you edit the the 'themes'. Then click on show advanced options. Below where you choose the picture, make sure that the 'repeat background' box is checked. Hopefully that should tile the pictures and fill up the background. Hope I have understood you and you have consequently understood me and it works :)
