Thanks for getting back on those thoughts and for your continuous work!

I realize this "property" would require a new field in the database, so probably a long shot indeed ;) I was just sharing ideas.

I already limit the dimensions of the pictures I upload, they are 1920 px tops, usually 1024 px.

Truth is, no matter what means are implemented, if a user sees a picture, it is already physically on their device anyway :)
