Three20 image from file folder

I am saving a UIImage using following codeThis image is saved in My application's Documents folder.

NSString *pngPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/Test.png"];
[UIImagePNGRepresentation(currentImage) writeToFile:pngPath atomically:YES];

How to get back this image in Three20 TTThumbsViewController? Somebody please help me. I am confused with the path of this UIImage.

I tried file:///Users/sijo/Library/Application%20Support/iPhone%20Simulator/4.0.1/Applications/869B4AE9-A3DD-4F42-868E-E8863B15FAC3/Documents/Test.png

But this image am getting in safari browser. But in my iphone app, its shows following error

[NSURLResponse allHeaderFields]: unrecognized selector sent to instance 0x7062d30 2010-08-27 20:29:04.304 Tides and Weather[56179:207] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSURLResponse allHeaderFields]: unrecognized selector 开发者_高级运维sent to instance 0x7062d30'
