The past few days have, in the end, been solved by a brute force attack on the visible code. A lot of people have been throwing around ideas for sequences of digits they think could be the solution. If you have the ability to run C# code I have attached a sample class above. with that you can alter this line: [quote]List<string> test = fromBrutes("/231500_4{4,5,6,8}1_9.jpg");[/quote] just change the extension to the known numbers - use _ for completely unknowns and surround the digits that you have some guess for with {}'s and end it with .jpg Not sure if we'll even need ti tomorrow but just in case - I don't expect them to give us the day off. User SheeEttin also gave me permission to link his python script which has similar functionality [url=http://www.mediafire.com/?ozu2o3plduip030]Python script[/url]
