There are two options for downloading your pictures:
(1) Download all pictures (in a .zip folder)
(2) Download specific photo
If there are a lot of pictures in an album, the system may ask you to insert your e-mail for it to send a download link. Clicking on the link, the pictures will be downloaded in .zip folder where you need to extract them later (for this you can use e.g Winrar).
If you have any trouble downloading the pictures, please contact me via e-mail firstname.lastname@example.org.
