@werthen: in what way are you planning to use this gem? The images above which most of the text is rendered are not part of this project right?

[werthen]

I was thinking of maybe extracting a primary color from the image, and then use the text color which contrasts the most with that primary color.

You'd have to fetch from the img url during compilatation to do that with a gem tough. That feels a bit finicky.

We should inline the images during compilatation as well then, which might be something we should do anyway.

Only when compiling in a production environment, but yeah, i'm not sure how to pull that off really efficiently. It would be a nice experiment

I guess these things need to happen in the preprocessor:

• Find all absolute links
• Filter those with image extention
• Download image
• Save image in output
• Replace absolute external link with internal link

This would also improve performance, since everything comes from the same domain.

This would definitely increase our compile time A LOT, but then again, we could cache these things in the output folder of the site. Extremely low priority but it would add another interesting layer to our static site by gathering external assets. Sort of related to #164, we could probably reuse a bit of the code to handle that link rot?

As long as this is only in a production environment, compile time doesn't matter too much I think. Is there a decent way to select only the url's from the latest changes? Also moving this to it's own issue.

[werthen]

not entirely, I think it will recompile every time, which might be a bit problematic. There's no way to get only the hash from a random image on the internet. Maybe this is a functionality we could add to ZEUSWPI?
