I've tested my solution and give me the answer: "Your pattern would match "wechallxjpg", but it should not match it."

Hi!
I can not find the way to remove 2 more character. The expression is okay, but too long. Can you show me the way?

/^wechall[4]?\.(?:jpg|gif|tiff|bmp|png)$/

Your pattern would capture a string, but this is not wanted. Please use a non capturing group.
