Thickbox 3.1 is excellent to use. However, it will load forever and ever and will hang there. After monkeying around with various things and checking that everything is linked. I searched and scoured google for some answers. The answer lied in the wordpress forum. Which i cannot find the link again for the life of me.
The issue was that Thickbox 3.1 uses jquery 1.2.6. The version that i was using 1.3.2. In order to correct this dilemma. You just remove the @ symbol from line 78. I’ve went to the longest yard and have uploaded the version for you to download: Thickbox-min.js (ZIP)
