I don’t have time to go messing about and seeing why it isn’t working at the moment so the quick solution is editing the jquery.lightbox.min.js file
Find the bit show_linkback:true in there and change it to show_linkback:false
In general I resize images before I upload them to WordPress and as a result I disable the click the image link. However I noticed no nice lightbox (click image and it pops up rather than taking you to a page with just the image) effect as so sent up a call on twitter if anyone knew a quick plugin that’ll work with existing content and hey presto twitter.com/thelinden ( Barry Walsh ) gets back to me in seconds mentioning ShadowBox JS. God I really love twitter sometimes can save you ages looking up things and making up a forum post and so on.
Cheers Barry and you can see the results on my previous post its automagic (Just needed to select JQuery in the plugin preference and it auto picks up linked images)
