I am trying to load the image(png) in UIWebview. But I got the following error ""ImageIO: PNGinvalid literal/lengths set"

I will get the "png" from the web service. I will store it in the following path. "Users/XXX/Library/Application Support/iPhone Simulator/4.3.2/Applications/E4DE3097-EA84-492F-A2A7-5882202F3B00/Documents/attachement.png "

When I reading the file from the path, I got the error. I am using the following code

  NSBundle *bundle = [NSBundle mainBundle]; 


  NSString *path = [bundle bundlePath];
    NSURL *baseURL = [NSURL fileURLWithPath:path];

    NSString *commentHtml = [NSString stringWithFormat:@"<img src=\"%@\"/>", documentEntity.path];
    NSString *html3 = [NSString stringWithFormat:@"<html><head/><body><div><b>COMMENTS:</b></div>%@</body></html>", commentHtml];
    [self.documentView loadHTMLString:html3 baseURL:baseURL];

Please help me.

THanks Girija

    As samfisher said, it's hard to help without the code. Also: if you're loading an image from app bundle please upload it to your question; if you're loading it from web please provide a link. Did you try to show the same image in a UIImageView? – Rok Jarc May 31 '12 at 09:15
  • For starters try the accepted answer here: http://stackoverflow.com/questions/747407/using-html-and-local-images-within-uiwebview (ie: without the extra html). Take a look at http://stackoverflow.com/questions/3808451/how-to-embed-local-images-in-uiwebview, http://stackoverflow.com/questions/5329648/display-local-uiimage-on-uiwebview also. – Rok Jarc May 31 '12 at 09:31

If you have saved the Image in Documents Folder, why are you fetching from MainBundle. Fetching Image from the Documents Directory would be : 

    NSString *aDocumentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    NSString *aFilePath = [NSString stringWithFormat:@"%@/attachement.png", aDocumentsDirectory];
    UIImage *anImage = [UIImage imageWithContentsOfFile:aFilePath];
