Add optional parameters to select which elements to embed.

Sometimes in posts on BSKY or Twitter, there will be content that isn't useful to the embed. It would be great to be able to say for example "only embed the first image". Sometimes posts on Twitter even have a few images and video, so being able to select which video you want to embed (since Discord doesn't support multiple videos in one element) would make that also helpful.

I could imagine a format like this https://fxbsky.app/profile/kiginobiru.bsky.social/post/3kkuvsr7h6h2w/f0110

Where 0 excludes that element and 1 includes it. Simple bitmask. So the second and third element would embed in that case.
So if someone wrote f1 it would embed only the first image/video and not the other 4. Or f01 for just the second.

Feels like it would be intuitive enough for the average person once they'd seen it done a few times.

This exists for Twitter because it respects specifying a specific embed, for example /photo/2. Bluesky does not have the same syntax so this would need to be implemented. Not sure if copying Twitter's scheme for this is a good idea or not.

I wasn't really thinking about it from the aspect of visiting the page and it showing that photo, just purely for the sake of further control over how something embeds, in which case there is access to the array of media elements to select with by number and feed the modified embed data to Discord for example. And if you visited the fxbsky.app URL, it already strips those extra parameters and leads to the post itself.
