Wildcard Subdirectories via htaccess

I'm trying to figure out how to have wildcard sub-directories on my webserver. In example:
domain.com/1/weiurfda83/
domain.com/1/weiu9234usd/
domain.com/1/fj4329fj/
would go to domain.com/1/ without redirecting
Also
domain.com/1/weiurfda83/1.jpg
domain.com/1/weiu9234usd/1.jpg
domain.com/1/fj4329fj/1.jpg
would go to domain.com/1/1.jpg without redirecting.
Any […]
