About attachments

[StarStorm]

Hey scamps! Recently I created a new character app, and ran into a problem while trying to add my art of her to the post. I've been wondering if there was a limit on how much data one may use in attachments, and if so, if it would be possible to delete old attachments in order to make room for new ones. Also, are there any tricks I can use to be able to just post a picture without adding to my media? Sorry if that's a lot of questions, or if any of them seem silly, but I just can't figure it out, and I'd really like to share some of the pieces I have
