Please provide details how it failed to detect a vaild jpeg file, eg which 9 bytes it read and what should be the 11 bytes.
jpeg addon should automatically use Qt if available. Otherwise it use pure J scripts. You could also use platimg or image3 addons of J602, however they are no longer maintained.
