Importing Images with Transparent Backgrounds

Please Help! How do I import images into toonboom 4 and get the backgrounds to be transparent?
Thank you

Use an image format that supports “alpha-channels” (transparent backgrounds),
like PSD, PNG, TGA etc…

Use Photoshop, or any other image editor (there’re many to choose from)
to delete the background and save to a file-format as mentioned above…
