The CSS is cached, so you get a different image only if you do a page
reload with force clear cache. If you want a different image when you
reload the page then you have to either keep displaying the image from
the page content or use JavaScript.

Hi,
Would like to set a backgroundImage dynamically
(I have attached 25 jpg files to a page)
If I add this velocity code into my wiki page it works!
{{velocity}}
[[image:Photos.CdLSWorldbanners@${mathtool.random(1,
25)}.jpg||width="100%"]]
{{/velocity}}
If I add this same code in a stylesheet extension object:
#document-title{
background:transparent
url($doc.getAttachmentURL("Photos.CdLSWorldbanners(a)${mathtool.random(1dom(1,
25)}.jpg")) no-repeat scroll right center;
}
I get this result if I inspect the CSS in the browser:
background:transparent
url(/xwiki/bin/download/Sandbox/change%2Ddocument/Photos.CdLSWorldbanners%407.jpg)
no-repeat scroll right center
Any suggestions if this CAN work, and if possible; what am I doing wrong?
Gerritjan
