ImageReadWriter class>formFromStream: was 
a) reseting the stream position, which may not be correct if several images can be present in the one stream. Change to restoring the position to what it was at the beginning of the method.
b) included ImageReadWriter as one of the classes asked if it understands the image format - since it always says no, pointless waste of time.
c) JPEGReadWriter and JPEGReadWRiter2 >both< understand the same format.
It is pure luck of the draw as to which gets to say yes first. If
JPEGReadWriter is obsolete it should be removed. If not, some
cross-check should be added so that JPEGReadWriter is only checked if
there is no plugin for JPEGReadWriter2.
