Can I just base64 encode the single image and then reference it in my HTTP::respond?

Of course. The data group is just a place to store the information, but you could just as easily include that "string" directly in the iRule.

when HTTP_REQUEST {
    if { [HTTP::uri] equals "/myimage.png" } {
        set img "...base64-encoded image data..."
        HTTP::respond 200 content [b64decode $img] "Content-Type" "image/png"
    } else {
        HTTP::respond 200 content "...some HTML that includes an image src tag for /myimage.png..."
    }
}

Or, if you wanted to get really crazy and not require a second request for the image, you could include the data inline in your HTML response:

img src="data:image/png;base64,...base64-encoded image..."
