You can use layers to add background images or colors into the document on one layer, then add another layer to edit text and other images. You find the layers tool on the toolbar on the right side.
- Click on Layers
- Add a new layer at the bottom right of the layers window.
NOTE: You have to make sure the layer you want to work on is selected. To be sure you’re not accidentally working on another level, you can click on the lock symbol on the other layers, before you select the layer you want to work on.
