I'm going to assume you have both Windows and Powerpoint

Take a thumbnail and expand it to the white area

Then get white backgrounds that are also .png's(note background has to be clear when placed on page)

Place both characters in preferred area

Save, then go to Save As, then go to Powerpoint Presentation, then when you're about to save again switch it to either a .jpg or .png

After that just upload the photo to the wiki and Done
