I feel like this is probably a really stupid question, but I’m just not sure what I’m doing… I want to make an expansion for a module, just adding some custom cards. I’ve played around and was able to add one card, so I think I can figure that all out, but the image I have is bigger than the existing cards, and I can’t tell how big I need to make the new card images. Is there somewhere where it will tell me how big they are, or someway to extract the images, so I can see their properties?

Thanks.

Nevermind! I just found a post that said modules are actually zip files, so I was able to change the extension to zip and open it up and get to the images. 🙂
