Mini-Photo Labs will actually do this process for you if you wanted yuo invest in that kind of money in one.\nThe labs that you find at WalMart or Walgreens actually have contracts to sell this metal to organizations that buy it on a regular basis.

Purify it. And then have it in a closed system where nothing can get to it

there are programs that can retrieve the images at a lowel format, you can try them for free, and if one works for you, buy  it, they don't cost but about 20.00, I use one called digital picture recovery for my clients, another one that works very well is photorecovery v3

If there's nothing in the Recycle Bin then you'll need an undelete utility.  Some are free, some are commercial.  Try the free and commercial ones listed in the sources, but try not to install them on the same device that you stored your pictures on.  (They may inadvertently install over whatever it is you wish to recover.)\n\nThen buy a DVD rewriter and set yourself a backup regime.  If you value it, duplicate it.\n\nGood luck.

Try changing the pH of the system and lowering the voltage.  If those don't help go the other way.\n\nhttp://www.cehs.siu.edu/Chemical/silver_waste.htm\n\nhttp://www.p2pays.org/ref/01/00048.htm\n\nhttp://www.finishing.com/73/82.shtml

Just google pollution and recylcing.  You can get images for your report that way too.

Use a program like CCleaner to clear all of your junk files, it will also clear those files you're taling about.  I posted a link in the sources for you.

Your best site would be the Office of Solid Waste at the US Environmental Protection Agency.\n\nhttp://www.epa.gov/osw/

call your local waste authority to see where you can take idems like that.  There are usually several businesses around that will take older hardware and make it new for other people in need to use.  It was very nice to think about something like that. :D

Return them to nature, bury, burn or make them an offering to a river or the sea. \nPeople buy old religious prints and statues on eBay but you can't know how they'll be treated or what they might be used for, if you don't really care about this you could make some extra dollars.
