[HOT] West African HOT Mapping Tips

Hi Blake
An other interesting design would be to use static images with arrows to move from one to the other.  

Nick LearnOSM design with arrows and text is very instructive. Like we do with Slides, arrows and texts could be added progressively. If it is not already the case, it should be possible to revise LearnOSM to use Javascript to control arrow instructions.

Hi Severin,

I can share all the originals ( I think/hope I still have them ).

That was my main mistake, the text on the images making the translation 

It was a process and you can see in later items the text came out of the 
images and went into the caption to make translation easier.

That is also the style Nick has implemented in LearnOSM: Numbered arrows 
for detail and clarity in the illustration, and then text explaining the 
details of the illustration and they look great.

As to the videos: I also have a few of those, not silent unfortunately 
:) But I have recently thought about doing short animated gif 
illustrations and passed around the Training WG email list a few tools 
that do that well.

Here is an example of tutorial with animated gifs that used something 
like the tools I passed around to the Training WG.

This example is busy ... maybe a bit too crowded for all the activity on 
the page, but gives a good idea of what someone can do with short 
animations for tutorials. Laid out better like Mikel's example of 
Bangladesh mapping and it could be very educational and low bandwidth.
