I am using the complete english wikipedia, without images. And the article "Boletus edulis".
You remove images completely, incl. the captions, which I think is good. You should probably completely remove "Template:Multiple image" too. See the first picture.
Would it be possible to include a selected few images in future non-image ZIM-files? I'm thinking about images included in some templates. If you include the few images used in "Template:Mycomorphbox" (see the second image), they would be included in thousands of articles at the cost of a few bytes. Other images that could be included would be pushpin-maps used in "Template:Infobox settlement". One map image is shown in thousands of articles.
Could you include coordinates? Now it is simply removed. They should probably not link to the special page for coordinates, and not show the mini atlas symbool. But the numbers is informative anyway. Also, it looks a little awkward right now, see third image.
Thx you for your feebdack, I agree with you. I will try to fix that problems.
