Once you've made a note of all the pictures you want (if you haven't, go back to the gallery and click on a photo to get its name), simply open the folder below, and click the little box to the left of the yellow file icon to select it. When you've selected all the images you want, click 'Download' at the top. You can re-order them by clicking on the 3 little lines below. Much quicker and easier than downloading them one at a time, dontcha think?
