Instructions

only tested in chrome

1. Set default download location to not prompt and folder to where you want files to be saved
2. Open album , and select image to go into large display view
3. For safety click the options button then just hover over the popup menu over the download link
4. copy script into console
5. change "10" at end of script to the amount of photos +/- 10 or so since the gallery loops around to be sure you get it all
6. leave everything else alone and run script.

To Note

script uses setTimeout which effectively waits 5sec , for safety , since unable to check if download completed.
could delay time when download starts to be sure image even loaded.
