Turns out I do have a specific question. I mentioned above I created the custom column to save metadata which is working fine. But...some of that data I don't really care about. Like the collections data.

I'm confused about how to exclude that.

If I don't want that collections data pulled at all...I want it either omitted or deleted from the saved metadata column, how do I exclude it or remove it?

Does just removing the collections entries from extra_valid_entries do that? Or do I need to do an exclude_metadata_pre/post of some sort?

Did some testing! So it turns out that if you edit a book in the calibre epub editor, there's a menu option to download any remote assets, which does all those steps in one go.

And yes, it turns out my kindle does show the background image just fine.... aside from resolution issues. Said resolution issues make this particular instance completely unreadable, but hat's just how things go.

I've included a screenshot.

From FFF's 'Saved Metadata column'? You can't control that, by design.

It contains everything FFF collected without any of the replacement, in/exclude processing so when you change your mind about what you want in your own custom columns, it's all still there.

You can tweak which columns Calibre searches by default in Calibre's prefs > Search if you want it to be more invisible.

I did look for that in Edit--it's down a Tools > External links submenu and I was looking for 'Download...'

FYI, that does the same thing as Polish book--it works, but next the FFF update will break it.

You know, I just remembered I added code to EpubSplit to find images in CSS a while ago. I wonder if I could make that work in FFF...

I'll look into it tomorrow.
One of the key parts of FFF's image processing is storing the original image URL to match duplicates in different chapters. We store that in the <img longdesc="origurl"...> attribute.

CSS url() includes don't have anything like that we could appropriate. Trying to store origurl in CSS comments or something seems both difficult and sketchy... We do have adedup_img_files setting now, but that doesn't save image downloads, just space in epub.

I know this has come up a couple times before (in 15 years), but how often are CSS images actually a problem?

ah, ok. I did find the setting to remove it from the book details section of the main display, so I guess I'm good.

and I managed to stumble my way to a replace command I'm contemplating. (Trying to decide if I want to just simply the Marvel fandoms and change all of them (Iron Man, Captain America, Thor, Avengers) to just Marvel or MCU. All the characters end up showing up in all the fanfics basically so...now just playing around with things.)

At some point I'll have to start checking some of the other sites I still visit, but right now my "new" personal.ini is only for AO3 since that is where I do the majority these days.
