In addition to some photos, I have a some graphic images that were created for me by a graphic artist. They include birds, butterflies, etc. I have them as jpg and png files.
As I understand it, the png files have a null (may not be the right term) background. I thought this would allow them to show up with irregular edges (not as a rectangle) so that I can place them on top of the photos and have the only the actual image visible (not a white or black rectangle).
SF won't let me upload png files and the jpg files come in as rectangles. Is what I am trying to do not possible?
