Oops, I've decided in my poster I want to place a picture behind all the text and pictures I've already got in there. How do I do this?
I'm trying to get everything to look like it's sitting on a desktop, so I want to paste a picture of my desktop (as in actual desk top, not computer desk top) in as the background.
We don't really know how your document is set up, so it's hard to make a fail-safe suggestion. But I'd suggest placing your image as usual, and then using Object -> Arrange -> Send to Back to move it behind everything else in your document. If you are using layers, you can make a new layer for your backdrop, and then drag your new layer to the bottom of the stack.
Select the picture,
Right Click on it , Go to Arrange-->Send to back
I set up layers and that did the job. Thanks
