Hey there!
Just bought Simple Image Gallery PRO, and tried adding a directory. The images are uploaded into images/stories/operation_wildfire/ so the code I've inserted is {gallery}operation_wildfire{/gallery}. It complains is I enter the wrong name for the folder, so I know that it's actually finding it. I've tried everything. Enabling and disabling the plugin, change names of the folder etc etc....

Why doesn't it show up??? :( It's really frustrating....

This is the html:

<p>Pictures from my travel to Australia</p>
<h4>Operation Wildfire</h4>
{gallery}operation_wildfire{/gallery}


This is the URL:

www.rocketmachinegun.com/index.php?option=com_content&view=article&id=57&Itemid=65



The plugin is at it's default settings....

Haha. It was the file extensions. Had to change from .jpeg to .jpg. Duh! ;)
