@NavinoEvans it looks like the issue here is that when there is a "Card" in the commons description we are reading that and not the actual description. Also and links that are in the card are lost.

Mmmm, interestingly this is exactly how it shows on the response from the API call, so something to be fixed at the source I think:
https://commons.wikimedia.org/w/api.php?action=query&titles=File:Algerian_Cousous_from_Biskra.jpg&prop=imageinfo&iiprop=extmetadata

I thought the cards would not show at all for any image (without more complex steps) as they are templates so no actual text on the page. But it seems to store the text with none of the inserted values (Algeria should be inserted by the template in this case).

@Anthere any more examples you find of a partially displaying text from a Card will be very handy. Just to check if there is an error on this one Commons item data, or if it's always like that.

Also need to check more examples of the "multilingual description" template this item is using. It seems like we simply don't get that data for "description" on the Commons API call.
I'm sure we can get the data by doing a separate templates query and reading the values from it, but all sounds way more complex than it should be!

Update: this is waiting on some research and feedback about the Commons API this is the root of the issue
