Suggestion. You can set a lot of default settings in a seed file. Create a seed file with some various settings of your choice such as, color palette, level names and groups etc. Each time you start a new drawing use the seed file as a "seed" :-)
Just a thought.
Suggestion. If you use 1/8" text height, place some text and then import the image and adjust it until the image text is about the same size as your text. This will bring the size to approx. what you need.
