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.

Hi Gonzalo,
Hmmm, interesting. You’re right it’s a good way to explore to reduce
the package size.
Plus, most of the times images are displayed in the game at maximum
70% of the real size. So, I’m not sure reducing quality will be
visible.
I’m going to try.
About list of contents, it could be find here: [1].
Best regards from France.
Lionel.

Hi Lionel,
Almost 65 MB are in the html/images/database directory, I think you
can reduce the size of these images to 1/4 of the actual size, just
saving as gif or jpg and playing a little with the properties, without
loosing too much quality.
I tried with one on gimp, but you can use imagemagick or similar to
reprocess all the directory
Look:
[gonzalo@localhost abc]$ ls -l
total 152
-rw-rw-r--. 1 gonzalo gonzalo 19228 abr 24 17:59 accountant2.jpg
-rw-rw-r--. 1 gonzalo gonzalo 16029 abr 24 17:59 accountant3.jpg
-rw-rw-r--. 1 gonzalo gonzalo 21789 abr 24 17:56 accountant.gif
-rw-rw-r--. 1 gonzalo gonzalo 28391 abr 24 17:57 accountant.jpg
-rw-r--r--. 1 gonzalo gonzalo 62549 dic 9 22:57 accountant.png
(accountant2.jpg is with quality 70% and accountant3.jpg with 50%)
I don't know about the audio, but maybe is possible improve there too.
I would like have the list of words represented on these images on
pootle. I imagine many activities
can use this if is a shared resource.

Hi all,
I’ve released last week my Abecedarium activity for Sugar 0.96
+. One issue with this activity is that, due to number of
contents (1500 images and sounds), its size is about 100Mo.
We want to deploy the activity on our Nosy Komba deployment
this year: 150 XO-1 and 50 XO-1.5.
Because we’ve got other activities to deploy, we compute:
- The free space on a XO-1 and XO-1.5 with Sugar 0.96
without any activity: 550 Mo for XO-1, 2645Mo for XO-1.5.
- The size of all activities that we planned to
install, see the spreadsheet [1].
Unfortunately 100 Mo is too big for the XO-1 with some other
big activities (GCompris, Tuxmath, TurtleArt, Speak, …).
So I choose to develop a new version named “Abecedarium
Net” [2] without any content included, so with a size of only
6Mo.
The idea is to deploy all contents on a school/web server
instead of into the activity. A config file in the activity
has to be set with the URL of the content, or it could be set
from a dialog popup. The activity test the network regularly
and display the status.
Because Abecedarium is wrote in HTML5, deploying the web
server just mean to copy the content of the full activity on
the server.
I’ve explained the full process in the activity description.
I will test it myself on our School Server at Madagascar but
do not hesitate in the meantime to test it and give me
feedback.
Best regards from France.
Lionel.
