I installed the Simple Image Gallery onto 1.5 using the "browse and upload" feature. I am relatively new to Joomla, so I have no clue what I'm doing.
When I try to use the gallery tags, all I get are the image tags in my content, ex:{gallery}folder{/gallery}
Did I install it wrong? Am I missing something? Any help would be appreciated.

Here's a silly question. Is it even compatible with joomla 1.5 yet? Havent seen any thing saying it was of now.
