Please do not upload non-PNG images to the wiki. You recently uploaded some .JPEG images of Brainstorm and Cannonbolt, which I have since deleted and replaced with .PNG images. Please read the rules (and by extension, the Image Guide) to prevent this from happening again.
You can convert .JPG images to .PNG using a variety of sites online, such as this one. In addition, assuming you're the same person as Jay, please choose one account to use, as the wiki has a rule against using multiple accounts.
