If your datePicture is of type UIImage, you could encode the image in base64 and embed that directly to your HTML.

NSString *html = [NSString stringWithFormat:
                   @"<html> <head>"
                   @"<style> body { font-family:Verdana;font-size:13px;}</style>"
                   @"</head>"
                   @"<img src=\"data:Image/jpeg;base64,%@\" />"
                   @"<br/>%@"
                   @"</body> </html>", 
       [QSStrings encodeBase64WithData:UIImageJPEGRepresentation((datePicture, 1.0)],
       strDescription];

Note that I'm using QSStrings to do the encoding, which can be found in QSUtilities on github
