Try NeoDownloader, you can setup filters and several rules to download only what you need.
It have a 30day trial and a Lite Free version.
When I find a directory/site, I use a few different tools depending on how its set up.
On a open directory, http://www.neodownloader.com/ is what I utilize. (Full version is payware)
Also, another app called "Free Download Manager" allows for specific url drag and drop downloads.
And yet one other is a addon for Firefox called "DownloadHelper".
Edit* "Down Them All" is a handy Firefox addon as well.
Try using the free version of Neo Downloader http://www.neodownloader.com/ . I use it all the time too bulk download albums on Imgur. All you have to do is copy the album url and paste it into Neo, choose the desired path for storing images and your good to go.
I use a program called neodownloader. I used to use a imgur specific album downloader but the lite version of neodownloader is free, easy to use, puts pics in a nice folder, and can download pics from any website.
