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

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?
Click for spoiler
/^wechall[4]?\.(?:jpg|gif|tiff|bmp|png)$/
Your pattern would capture a string, but this is not wanted. Please use a non capturing group.
