After the upgrade Xampp with 1.7.2 final to 1.7.3 beta 2, after attempts to upload pictures (Datalife Engine) in the apache logs are written "JPEG parameter struct mismatch: library thinks size is 472, caller expects 432" (as a consequence of the picture is not reduced and not loaded)
I understood the problem with the library gd2.
p.s. Translate with Google® (RUSSIAN users)
