Hi Stefan,

	I've open the SqueakAddOns MC http respository at squeaksource but
all versions gives the EOCD or cant read the stream.

	Do you know if that repository is in a normal state?

	I really want to be able to resize uploaded (to an app) images and
store them in a standarized (expected for the application) way and I think
Smagik can help for that.

	cheers,

Sebastian Sastre
