I have been through a selection of Google results and all I seem to come across is using CSS. I have tried doing this, using just one image and making the style slide it along to create the rollover effect. I have tried this to no avail. I put the relevant CSS in style.css in the Editor and then added divs to the header table with class="header-tw" (Twitter button) and other things the websites I used told me to add.
I'm just wondering if there's any way of making either the browser pre-load the images as the page loads (to eliminate the delay, I can live with no fade), to get the CSS working (any ideas?) or even another method. If possible I want to stay away from Flash under all circumstances as I wan't my blog to be universal device wise.
Thanks in advance.
