Maintenance/sorry page with image on v11

Basic maintenance page:

when HTTP_REQUEST {
        if { [active_members [LB::server pool]] < 1 } {
                HTTP::responsd 200 content "Down for maintenance"
        }
}

So if you want to serve up an image with a basic maintenance page, it gets a bit trickier. What I do is upload the HTML for the maintenance page and the image as iFiles and reference them in the iRule. For example, if I have a page that says "Sorry! Down for maintenance!" and has an img tag that calls for "myimage.jpg", I upload both to the F5 and convert them to iFiles, and change my iRule to something like this:

when HTTP_REQUEST {
        if { [active_members [LB::server pool]] < 1 } {
                switch [HTTP::uri] {
                        "/myimage.jpg" { HTTP::respond 200 content [ifile get "myfile_jpg"] }
                        default { HTTP::respond 200 content [ifile get "maintenance_html"] }
                }
        }
}
