Keeping it simple.
What I wanted to achieve is a simple function where if an image is included in a post clicking on it would create a modal window. I'm not bothered at this point whether it's Thickbox, Fancybox or whatever. The simplicity is the important bit.
This could have been achieved using Auto Thickbox Plus but the Fishpig/Margento bridge we're having to use doesn't support that. It does support NextGen.
Could somebody please advise. We don't need the extensive gallery functionality, just the modal function.
I have installed NextGen Colorboxer and NextGen Gallery
