Yes. UIWebView has two methods: -loadHtmlString:baseURL: and -loadData:MIMEType:textEncodingName:baseURL:

You can get the file data using NSData's -initWithContentsOfFile:, then pass it to the latter of those methods above.

EDIT: Whoops, I didn't notice the img part. But it still should work. Are you trying to load only the image?

    NSData *htmlData = [NSData dataWithContentsOfFile:filePath];  
    NSString * html =  [NSString stringWithContentsOfFile:filePath encoding:NSStringEncodingConversionAllowLossy error:nil];
    if (htmlData) {

    }
