I've been trying to load images from a url using ASIHTTPRequest but I always come up with a blank UIImage. I think it might have something to do with iOS automatically choosing the @2x named version of images or vica versa.

[ASIHTTPRequest setDefaultCache:[ASIDownloadCache sharedCache]];


NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]];
NSURL *url = [NSURL URLWithString:url_string];
__block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setDownloadCache:[ASIDownloadCache sharedCache]];
[request setCachePolicy:ASIAskServerIfModifiedCachePolicy|ASIFallbackToCacheIfLoadFailsCachePolicy];
[request setCacheStoragePolicy:ASICachePermanentlyCacheStoragePolicy];
[request setSecondsToCache:86400];
[request setDelegate:self];
[request setCompletionBlock:^{
    NSLog(@"Successful Update");
    [self makeAssignment];
}];
[request setFailedBlock:^{
    NSError *error = [request error];
    NSLog(@"%@", [error localizedDescription]);
    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Update Failed"
                                                    message:[error localizedDescription] 
                                                   delegate:nil
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
    [alert show];
    [alert release];
}];
[request startAsynchronous];
NSLog(@"%@", url_string);

The makeAssignment method is below.

NSString *url_string = [NSString stringWithFormat:@"http://173.246.100.185/%@", [eventDictionary objectForKey:kEventDescriptionImageURLKey]];
NSURL *url = [NSURL URLWithString:url_string];
downloadedImage = [[UIImage alloc] initWithContentsOfFile:[[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]];
NSLog(@"%@", downloadedImage);
NSLog(@"%@", [[ASIDownloadCache sharedCache] pathToCachedResponseDataForURL:url]);

Nothing I do, including naming images @2x on the server or providing both versions, gets it to load. Any ideas? Has anyone done this before? When I load them locally (from within the package) I don't have any issues.

Thanks!
