Custom lock icon no longer showing

[ex_prettygoodyear337]

 I have used this code in my CSS for a few years now, which always worked to replace the standard lock icon on entries with a custom made one:

img[src*="http://www.dreamwidth.org/img/silk/entry/locked.png"]  {

width:0;

height: 0;

background-repeat: no-repeat;

background-image: url(http://i148.photobucket.com/albums/s37/twinklewitch/lock1.gif) !important;

padding: 11px 13px 0 0 !important;

text-decoration: none;

}

 

img[src*="http://www.dreamwidth.org/img/silk/entry/private.png"]  {

width:0;

height: 0;

background-repeat: no-repeat;

background-image: url(http://i148.photobucket.com/albums/s37/twinklewitch/stop.gif);

padding: 11px 13px 0 0 !important;

text-decoration: none;

}

For some reason this doesn't work anymore, since my journal now shows the standard locked icon on all entries. Anyone knows how to fix this?
