Hello, I have about 180 sprites of a character that I need to put at double the size. Is there any online or Photoshop-type program that can add several at a time and convert them directly to the size you tell it?, so I don't have to go one to one.
You can do it with actions in photoshop, but I believe it's easier with a program called Irfanview, take a look at it's batch functions.
