The plugin does in a way work as in showing the images properly, but WP display the following notice:
Notice: Use of undefined constant ICL_LANGUAGE_CODE - assumed 'ICL_LANGUAGE_CODE' in /Users/Jan/Sites/wordpress/wp-content/plugins/wp-jquery-lightbox/wp-jquery-lightbox.php on line 71
I'm not an expert on Java or PHP, but I guess this means that something is not right. Rigth?
The plugin is great, but personally I would prefer not the fancy "animation", that the box starting from the top in the browser window and slide downwards. I think simplicity is a great thing, more like the "original" plugin of Rupert Morris. Also it would be really great to have an option to choose "themes" like Rupert Morris did.
Basically, what I was looking for in the wp-jquery-lightbox plugin, was a straight up ported jQuery version of Rupert Morris plugin.
Best regards, and thanks for your contribution to the WP community.
