Default [Q] Download manager like PC's Flash Get

Hello, I'm looking for a download manager working like Flash Get from PC. Especially, it has to have ability to detect all downloadable stuff on thw website and let me choose which one to download. I.e. if there is 4 sample vids, 30 pictures in a gallery, I like to choose *.jpg to make manager download all pictures at once, not like other apps click file after file.
