Reading image metadata from web URL

Been looking around and can't find a definite way to do this... I need to read the meta data from an image found at a certain URL. Is there a way to do this on the iphone?

I tried using iphone-exif and it just wasn't working in my project. Saw a lot of people getting the same errors as me.

Good news is I found another solution...

    NSDictionary *IPTCDict;

    NSString *urlString = @"http://SOMEIMAGEURL.jpg";
    NSMutableData *photoData = [NSMutableData dataWithContentsOfURL:[NSURL URLWithString:urlString]];
    CGImageSourceRef source = CGImageSourceCreateWithData((__bridge CFDataRef)photoData, NULL);
    NSDictionary *metadata = (__bridge NSDictionary *)CGImageSourceCopyPropertiesAtIndex(source, 0, NULL);
    NSLog(@"Meta: %@", metadata);  //Will print out all the metadata

    // Pulls out the IPTC data
    IPTCDict = [metadata objectForKey:(NSString *)kCGImagePropertyIPTCDictionary];

    NSLog(@"Caption: %@\nCopyright: %@", [IPTCDict objectForKey:@"Caption/Abstract"],      [IPTCDict objectForKey:@"CopyrightNotice"]);

Try this: http://code.google.com/p/iphone-exif/

You should be able to fetch the image properties (metadata). Hope this helps :)
