How can I download all photos from their LINKS on a webpage?

Is this a trick question or did you miss the big blue download button?

Yep, I did and usually it zips them up into one nice file and downloads that.  But because there are so many files it says it's too big to zip into a file and it gives me the option to copy them to my own DropBox... which I would if I had any room left.

I ask, because this may be occurring more than once.

May I ask how they can be too big zip?
What zip program do you have?
7 Zip on windows 7? it's free

Winrar not free but does have a fully functioning trial you can use, winrar can zip gigs and gigs of files great for very large archives even games and movies.

If you  download each folder in a zip then open the next folder do the same click on the download.
That Way you'll get a smaller download zip for each folder named folder 1 folder 2.
I tested other avenues such as highlighting them all within a folder then rightclick them and save as it only downloaded one image, I believe because they all have a link to a larger version  you need to use the download folder.
They have set it up so you can download each of the folders.

I'm not saying their too big to zip, the website (Dropbox) says that it would generate too big a zip file to download.

It is either going to be right clicking for 10 minutes or pay for dropbox.  What are you leaning towards?
