Unable to change product mock up

[teecee]

Hello

My name is Fountain and i am a new seller on zazzle;

Okay so am done with my first product design and all but i just realised that the mockups given to me by zazzle are not as attractive as i want it to be so my question is how can i change those mockup to what ihave already on my device

I think you can find the info you need here: Learn About Media Manager (zazzle.com)
