    Had an extra ] at the end of the third if statement. This should fix it for you.

    when HTTP_REQUEST {
  if {[class match [HTTP::header User-Agent] contains abcd_useragents] } {
    if {[HTTP::cookie MobileOptOut] eq 1} { return }
    if {[URI::query [HTTP::uri] MobileOptOut] eq 1} { return }
    switch -glob [string tolower [HTTP::path]] {
      "*.jpg" -
      "*.gif" -
      "*.png" -
      "*.bmp" -
      "*.ico" { return }
    }
    HTTP::redirect "http://m.xyzdomain.com[HTTP::uri]"
  }
}

If I was to refresh it would look like the below. The problem with the filetype match against HTTP::uri is if your URI is /page.jpg?value=1 it will fail to match, you need to match against HTTP::path which is everything up to the "?" in the URI. The return command below just mean to exit this irule.

when HTTP_REQUEST {
  if {[class match [HTTP::header User-Agent] contains abcd_useragents] }
    if {[HTTP::cookie MobileOptOut] eq 1} { return }
    if {[URI::query [HTTP::uri] MobileOptOut] eq 1]} { return }
    switch -glob [HTTP::path] {
      "*.jpg" -
      "*.gif" -
      "*.png" -
      "*.bmp" -
      "*.ico" { return }
    }
    HTTP::redirect "http://m.xyzdomain.com[HTTP::uri]"
  }
}
