Photos and graphics with transparent backgrounds will have to be created in a photo editing application such as PhotoShop before you can upload and use them in the yearbook.
Create the image with a transparent background and save it as a .gif or .PNG file. Upload the image as a photo to Treering.
When the image is first placed on the page it may not show as transparent. The frame option must be turned off.
You can use the frame to create a raised or 3D effect of the transparent image by turning the frame on and adjusting the visibility of the frame.
