Hey guys, this is my first animation. A little eye that I did in Opentoonz last night, just figured out how to render it out into gif today.

I haver a question about onion skins and layers. Any answer would be really appreciated.

On Onion Skins: It seems that it will only show me about 6 skins back, even when i select all of the frames manually, is there a way to make opentoonz show all skins at all times? (I want to animate a ball bouncing on a ledge, but by the time my ball gets to the ledge, I cant see the ledge anymore because the onion skin for it is gone.)

And on layers. I want to animate over an imported image, I tried a bunch of stuff but cant make it stay in the background, and it seems like I have to re upload it to every frame, which is just brutally time wasting, anyone know how to do this?

Any answer would be great!
