css - Border image not showing -

i'm trying have customized image border it's not showing. sure id i'm using correct, because when tried border-style:solid; black lined border showing.

#panel-902-1-0-1 {     border-width: 50px;     padding: 10px;     border-image: url(bg-trailed.png) repeat; } 

the image in same folder css file.

edit: revised.. realised misunderstood question completely. trying use border-image.

border-image-source: if value ‘none’ or if image cannot displayed (or property doesn't apply), border styles used; otherwise element's ‘border-style’ borders not drawn , border image drawn described in sections below.

looks may have hit one, suggested above, fiddle helpful.
