The cross posting issue is due to the fact that any two lemmy posts that point to the same url are automatically collapsed into a crosspost. This is the main reason that I have rikka set to not have any links pointing to the images. I thought it would be a nice feature, but the crosspost thing prevented it.

To disable having an image link when the bot makes posts, you want to set submit_image = none in the [options] section of your config file.

Now that 0.19.4 is live on this instance, I wonder if the thumbnail links are handled differently. I will have to do some testing around that.

As for language id, here is the page where pythorhead has all the language ids listed out.

edit: as of now, pythorhead doesn’t support setting a thumbnail url separately, so that won’t be possible yet.
