DL2 Custom Content

So, i had a DL2 recently to try out. I'm going to be using 2 for the first time on a show in April/May. I will have a lot of custom images and videos to upload to the fixtures. I got the hang of the DL2 quickly and was working with the standard content just fine. Then i wanted to try to use a custom picture. So, using CMA i was able to drag and drop it from my pictures folder on my laptop to the i think it was users objects folder. I never was able to figure out how to get it to appear on the DL2. Hope this makes sense.

I'm sure someone out there can help me.

thanks.
