First get the PNG, then go onto the wiki, hit the contribute button, then hit "Add a photo" and then upload it to the wiki there, then go to the card and post the file name in the template. OR, go to the card page first, upload the PNG in a comment, then put it in the template.
Sorry about the white background, but I had to crop it because all that extra space from the image when putting it in Additional Information bothers me. I don't have a lot of experience with photoshop, I had to put most in .JPG due to not being able to upload it in PNG (Ex. PHY SSJG Goku).
I apologize, but this is the closest I can get to uploading the quotes without leaving space in Additional Information and being big enough for people to see without squinting.
Reason I did it with the white background was because I couldn't find any site (at the time) that could help crop out the quote, so I had to us MS paint. Thing is when I crop it there, the white background stayed.
Can you delete images? If so, can you go delete the pictures that are jpeg?
