I have seen that a wiki's wordmark can be randomized through the use of this code: // Randomize wiki logo $( function ( ) {     var images = [        'http://images.wikia.com/vocaloid/images/6/65/Galaco_logo.png' ,        'http://images.wikia.com/vocaloid/images/9/94/Miku_logo.png' ,        'http://images.wikia.com/vocaloid/images/1/12/Yukari_logo.png' , 'http://images.wikia.com/vocaloid/images/7/7b/Sonika_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/1/18/Vy1_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/3/38/Pico_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/8/8b/Tianyi_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/1/15/Mews_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/d/df/Seeu_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/2/25/Akikoloid_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/0/06/Oliver_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/4/42/Lapis_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/9/98/Rion_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/0/03/Maika_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/6/6f/Big_al_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/7/7b/Brunos_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/5/5b/Cul_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/5/54/Ia_logo.png' <span class="sy0" style="color:rgb(51,153,51);">, <span class="st0" style="color:rgb(51,102,204);">'http://images.wikia.com/vocaloid/images/4/49/Mayu_logo.png' <span class="br0" style="color:rgb(0,153,0);">] <span class="sy0" style="color:rgb(51,153,51);">; $<span class="br0" style="color:rgb(0,153,0);">( <span class="st0" style="color:rgb(51,102,204);">'h1.wordmark a img' <span class="br0" style="color:rgb(0,153,0);">) .<span class="me1" style="color:rgb(102,0,102);">attr <span class="br0" style="color:rgb(0,153,0);">( <span class="st0" style="color:rgb(51,102,204);">'src' <span class="sy0" style="color:rgb(51,153,51);">, images<span class="br0" style="color:rgb(0,153,0);">[ Math.<span class="me1" style="color:rgb(102,0,102);">floor <span class="br0" style="color:rgb(0,153,0);">( Math.<span class="me1" style="color:rgb(102,0,102);">random <span class="br0" style="color:rgb(0,153,0);">( <span class="br0" style="color:rgb(0,153,0);">) <span class="sy0" style="color:rgb(51,153,51);">* images.<span class="me1" style="color:rgb(102,0,102);">length <span class="br0" style="color:rgb(0,153,0);">) <span class="br0" style="color:rgb(0,153,0);">] <span class="br0" style="color:rgb(0,153,0);">) <span class="sy0" style="color:rgb(51,153,51);">; <span class="br0" style="color:rgb(0,153,0);">} <span class="br0" style="color:rgb(0,153,0);">) <span class="sy0" style="color:rgb(51,153,51);">; However, I am curious to know: is there a way to make this code affect the wiki's header background instead?  For instance, randomizing multiple backgrounds images like this: http://img2.wikia.nocookie.net/__cb20140511024820/the-iron-giant/images/c/c4/Menu.jpg<ac_metadata title="Is it possible to randomize a wiki&#039;s header?"> </ac_metadata>
