If the info below does not help, please contact support with a link to the problem page. This can be a difficult issue to resolve, and sometimes requires the support staffs attention.
When the gallery page loads, javascript makes the big image display and controls the movement of the thumbs. If both of these do not work, it is likely there is a javascript conflict with another extension on the page. The cause of these javascript issues is usually related to the javascript library mootools and the javascript library jquery. The gallery uses the mootools library that is packaged with Joomla.
Problem situation one: There is no mootools library. The gallery tells Joomla to make a link to mootools (media/system/js/mootools.js), but some templates are programmed to remove this link and make a link to their own jquery file. You can see if this is the problem by looking at the html source of the problem page, and searching for the word "mootools". If it is not there, it is likely mootools is missing. Please turn any html compression plugins off before doing this. Ideally templates should use jquery in no conflict mode, and they should not remove the link to mootools.
To resolve this issue, please see if you template has a paramater to include mootools and set this to yes. Otherwise please contact your template developer to see where mootools is removed, or send Ignite gallery support a site login, and we can see where this is removed. The most common way templates remove mootools is with this code in the templates index.php file:
Removing this code may fix the issue.
Problem situation two: There are 2 mootools libraries. Some templates or modules make a link to their own mootools library instead of using the one that comes with Joomla. This creates problems, as there can only be one mootools library per page. To see if this is the case, please view the html source of the problem page, and search for "mootools". If there are two files with mootools.js in the filename, then it is likely there are 2 mootools libraries on the page.
To fix this, please contact the other extension developer, and ask them how to change their extension so it uses the mootools that comes with Joomla, or send Ignite Gallery support a site login so we can try and change this.
Problem situation three: There is jquery and mootools on the same page. If jquery and mootools are on the same page, one of them needs to use no conflict mode to make them work together. To see if this is the problem, please view the html source of the problem page, and search for "mootools" and "jquery". If you have both, there may be a mootools/jquery conflict.
To fix this issue in Joomla 1.5, please activate mootools 1.2 mode in the component paramaters and also turn on the mootools upgrade plugin that comes with Joomla 1.5.20. This may resolve the conflict. The Joomla 1.6/1.7 version is already programmed in a way that usually will not conflict with jquery.
