[Sugar-devel] Network version of Abecedarium: why and how

[David Rodríguez Álvarez]

Hi, Lionel

Besides any other optimizations, for a really quick and remorseless fix,
you can run your images through Trimage, http://trimage.org/ , which
uses some lossless compression libraries and seems to work nicely with
your png resources (see attachment for an admittedly too small sample of
results from your files, with impossible recursion added for fun).
 
Best regards,

David Rodriguez.
