 Are you uploading this changes to git? can I take a look?

 Btw is there any plan to implement images rendering?

 Math (images) are on our roadmap. Hopefully before the end of this
 year. The screen is only 1bit. So anything else would look kinda
 funny.

 Well due I have clear than Internationalization and running other apps
 are totally posible and in fact it can be done without much hacking, I
 have spend some time investigating the posibility of  include image
 other than maths on the device and I think is at least more closer
 than it can seems.
 I have find a process[1] I think it can be industrialized to transform
 any image of the wikipedia to one more or less good to the device is
 clear than we can expect a real time 3D zoomable render on the WR but
 I think results are quite promising
 
 Just some questions, is hard to do a image viewer able to scroll
 vertically as we do in text?
 Any good tutorial of scripting using gimp?
 
 An now some numbers the average image are 10kb so with the hypotesis
 than there are one image per article (yes I know there articles with
 more than a image but there a lot of articles without images) there
 will be about 3.000.000 images so 30Gb of images :P there are any
 32Gb uSD cards out there?
 I have to do a more in depth analisis on how many images(meaningful)
 are there using the data on the dumps of wikipedia  so we will see.

This is an awasome idea David, but you have first to consider two things:

1- Not all English wikipedia images are under a cc license or similar.
There're a lot of copyrighted images: logos, photograpsh, captured images
from videogames...
You've one warning in this wikipedia page:
http://en.wikipedia.org/wiki/Wikipedia_database#Images_and_uploaded_files

2- It's possible to automatically download all the wikipedia images using a
program called wikix (http://meta.wikimedia.org/wiki/Wikix) but someone
tried it back in 2007 and  the result had a size of ¡¡407 gb!!
(http://yousefourabi.com/blog/2007/10/download-all-wikipedia-images-with-wikix/).
Then, the task of downloading all the images and convert them should be done
with a very good machine or cluster.

PS: I know that for spanish wikipedia copyrighted images are not allowed and
we don't have the point 2 problem :P
