This is why we do test versions.
I noticed that the fimfic API returned metadata included 'full_image' and 'image' URLs both for that first story you asked about. Since full_image was a link to a larger version, I assumed it would be better to use that for the cover image. But not all stories have 'full_image', apparently. So now the fimfic adapter falls back to 'image' if there's not 'full_image' given.
Unchecking "Include images in EPUBs" stops FFDL from trying to d/l the image at all, that's why that worked.
The "Include images in EPUBs" checkbox, as it says, is exactly the same as adding:
Code:
[epub]
include_images:true
keep_summary_html:true
make_firstimage_cover:true
...to the beginning of your personal.ini
The '#' at the start of an ini line comments it out. You have to remove that for them to actually work.
keep_summary_html:true does
not include images. include_images does that. keep_summary_html just lets there be images in the summary, especially for make_firstimage_cover to find.
fimfic is one of only two sites to have official 'cover' images. The other 70+, if they have them, are either in the summary or the first chapter. That's why these options probably seem a bit weird to you.
This version should fix the full_image issue.
