Help adding photo to template!

I created and have been editing this wiki's page for Tokyo Crash Mobs. I accidentally added a picture of the game's Protagonist instead of the logo (You can still see that there). I took out the name of the file in the template's coding,and replaced it with the name of an image if the game's North American Logo. In the preview,it appears as "200.px",being a link that doesn't do anything. I dragged the picture from my desktop into the "Image" box,and it doesn't have the file,just information about my profile on my computer. I took it out,not wanting anyone to see personal imformation,leaving the image box blank. I added the photo through the "Contribute" option. Would I just need to put that file's name in there?
