It uses matlab to search a particular url for photo links (actually it looks for the thumbnail links and modifies the string to give you the full res photo link), then uses a system command call to wget to download the photos All in 8 lines of code!
Ok to start you need the full url for your album. The '?start=all' bit at the end is important because this will show you all the thumbnails on a single page. Then simply use regexp to find the instances of thumbnail urls. Then loop through each link, strip the unimportant bits out, remove the 'th_' from the string which indicates the thumbnail version of the photo you want, and call wget to download the photo. Easy-peasy!
