What display type are you using in MaxiGallery?
Here’s a list of the default embedded display types and what js libs they use:
lightboxv2 uses prototype+scriptaculous
slimbox uses mootools
smoothgallery uses mootools
slidebox uses prototype
Every embed display mode collides with jQuery, so you will have problems if you are using an embedded display type.
If you really want to use embedded display type instead of normal one, you can fix it easily by using ThickBox as your custom display type,
here’s info. It uses jQuery, so all you need to do is get thickbox.js, thickbox.css and the loadingAnimation.gif from it’s
homepage and add the .js and .css to your template <head> (or use maxigallery &css and &js parameters)
