Changing how opera handles filetypes with a bookmarklet / button / magic

Hi, I have been looking for a way to easy save loads of pictures to a folder without too much hassle forever.. I first tried to a shortcut or something to save a picture to a specific folder / opera download folder, but did not make it. However, I found out that I could automaticly download specific files to folders of my chosing. This is amazing, I must say, Unfortunately, I cannot see the pictures that opera is saving in the browser itself. So I got a few questions then:

1) The worst way:
Is it possible to make a button that makes jpegs save into a specific folder, and with the click off a button change it to open with opera?

2) Best way:
Is it possible to save every .jpeg / filetype of my chosing to the folder I decide, and still open with opera. So if I click the link (eg: http://kjelltrygve.com/wp-content/uploads/2007/11/opera4.jpg) it would still show in opera, but also (without me interacting) download to C:\bigimagefolder\ .

3) Almost as good:
Right now I am surfing with the speed of light thanks to my mousegestures.
Right Click > Right = Close page and switch to previous tab
Right Clcik > Left = Switch to previous tab.
If I could get / make a mousegesture that would do = Save (image) to downloadfolder, close page, switch to previous tab, that would also be really lovely!

If anyone got a solution, I would be most thankfull!
