I successfully installed Simple Image Gallery 1.2.1 for Joomla! 1.5. I enabled the plugin in the Plugin Manager. I opened an existing item to edit, then switched to the 'Image Gallery' tab. By clicking the 'Browse...' button I selected a zip file with 2 JPG images. I clicked the 'Apply' button on the toolbar.

The following error message was the result:

UNKNOWNARCHIVETYPE
Gallery upload error: Cannot extract archive!

How should this be fixed?

Environment: Apache 2.2.11, PHP 5.2.9-2, MySQL 5.1.33, Joomla! 1.5.11, Firefox 3.5, WampServer 2.0h

Does your server support gzip?

Of course, Ivo.

Hi. What version of K2 are you using? Can you please attach the zip file you are trying to upload?

Hi, Lefteris!

I'm using the latest, the best and the most beautiful K2 version (2.0.0 pre-release) :)

The zip I tried to upload is attached.

I uploaded your zip file with no problem. So the only thing i can do know is guessing. Can you check the permissions on folder media/galleries?

Lefteris, as I know, there are no file/folder permissions on a Windows localhost :)

Which Simple Image Gallery version are you using? Have you tried a clean install with SIG 1.2.1 and the K2 2.0.0 pre-release?

Sorry, Only the SIG Pro V.2 + will work for you

I suspected this. Thanks, Followeyes.

I had this same problem. When uploading to the gallery, the mime type is checked and it appears that it was checking the path for the mime type and not the name of the file. There are several checks for mime type prior to the code I edited below, and even some after. It keeps trying different ones until it gets a hit. Unfortunately until I fixed the code, it was trying to call it a text file and not a zip file. Anyway, this is what I did:

File: \administrator\components\com_k2\lib\class.upload.php
Line: ~2231
Change...
$this->file_src_mime = mime_content_type($this->file_src_pathname);
...to...
$this->file_src_mime = mime_content_type($this->file_src_name);
