What is the difference between "Download" and "Download source" on the toolbar when a file is selected?
"Download" and "Download Source" are found as two available buttons when one clicks the checkbox to select an image in your gallery. The "Download" button will download the most recent version of this image that you have have saved, and only as a *.fibps file format. The "Download Source" button will download the original version of this image. That is the file (and file format) that you originally uploaded.
