Help for Tabletop Simulator

I've tried to upload the image file for the decks in Tabletop Simulator. But the deck uploaded always cut at the wrong proportions. Is there some kind of mod from the workshop should i be using?

I'm not overly familiar with how TTS works honestly but I based my work with help from a guy on reddit: https://www.reddit.com/r/cardfightvanguard/comments/ogs29t/presenting_vanguardcardio_a_cfv_deck_building_and/h4lqayu/

He claimed it worked flawlessy on 2 TTS mods that he is using.  

It works. I just realized, i need to toggle the width and height settings in the game. Other than that, i have to crop a bit from the image. Overall, it worked perfectly.

Thanks.
