I have had a couple of people ask how i have downloaded pictures and videos from sites like tumblr, and i assume many more!
just google it!
bit of a bummer but the trial will only download a max of 200 items per website without paying, from memory $40 us
but it will save you a massive amount of time if you do end up using it!
can also be used on websites that require a login!!
i myself am still learning so i wont post to much information but
all you have to do is copy and paste a url and answer some basic questions..
It's actually called NEODOWNLOADER (no spaces). I'm going to try it out and also some alternatives. I think you have found a great utility which will save a lot of people a LOT of time!
