Can effect be applied to core code?

for this you must make an override of your component, but I also see that there is no image ... image effect CK works only with images

all the color boxes with titles in are images inside the js-image class

I tried this
<img class="effectck-lily" src=" alexanderrhodes.co.uk/Fresh/jsjobsdata/d...mp_6/logo/orange.png " title="orange">

cannot get it to work

right, I did not see the image at first

it should work but the code that I see in your page is
<img title="orange" src=" alexanderrhodes.co.uk/Fresh/jsjobsdata/d...mp_6/logo/orange.png ">

so it seems that your override does not work or something else is wrong becaue the css class is not rendered

i was trying it in firebug first to see if it would work, as the jobs.php code is a bit more complex to edit for me, so wanted to just prove it would work based on giving it a class...but it didn't in firebug? any suggestions to help get it working?

no it does not work like this in Firebug because there is some JS to add the needed code to the image
