An image can be inserted onto the current layer or imported onto a new layer.
If you have an image you would like to add to the current layer, ensure that in the preferences Add Image: import into a new layer is not checked.
The Add Image window appears.
You can select TIFF, Bitmap (BMP), JPEG, GIF, or PNG files.
The Transform Layer puck is available for you to place the image how you want it.
The image is “baked” into the current sketch, meaning you can no longer rotate, scale, or move it on its own. If you do not like its placement, choose Undo and try again.
If you have an image you would like to add that needs to be imported to a new layer, in the general preferences, you can set an option to do this. When Add Image: import into a new layer is not checked, an image added using File > Add Image... will be imported onto the current layer.
