I am learning my way through K2 and loving it.  However, I have a problem that many have reported, and yet despite several hours searching the forums, I have not found a straightforward solution.I'm using Joomla 1.5.20; K2 2.4.1; SIG Pro 2.0.5I am developing a product catalog and for each item, I want an image gallery of different views.Everytime I try to upload a zipfile under item>image Gallery, I get the standard error message:

UNKNOWNARCHIVETYPE
Gallery upload error: Cannot extract archive!



I am using WinZip to create the zip file; I have created a folder media/k2/galleries and set that as the default in SIG; permissions are 775.  I have uninstalled and reinstalled SIGPro.What more should I be doing to get this to work?Any help would be much appreciated - maybe a tutorial or documentation article would be appropriate as everyone (it seems) appears to run into some kind of image gallery problem.Many thanks,Andrew

First, be sure about the way your zipping up the jpg's
do not put them into a directory within the zip file

As far as I know I am not. I have five jpgs per product. I highlight them and create a zipfile in the same directory as these images that contains the compressed files. I then try to upload the zipfile and it fails.

What else might I be doing wrong?
Thanks,

What browzer are you using, i see in some of the posts here searching for Unknown.....
that switching browzers sometimes works

firefox for setting up the site

Tried it in safari and IE8 - didn't help

I've also tried various different configs for WinZip 12 and 14.5 to create zip and zipx files with and without compression - these also all provide the same error message.

Thanks...getting desperate!

Please if there is anyone with any suggestions as to how to fix this, I would greatly appreciate it. The site is now "live" at batrboots.com - although still in a very rudimentary state. If I cant fix the problem, I will have to give up K2 as my client is chomping at the bit.

I have tried an install on another site hosted by the same ISP and it didn't work...I tried it on a different ISP and it worked fine...what are the potential differences I should examine between ISP's. Both are running php 5....

I'm desperate....

Thanks,
Andrew

This solution worked - for some reason the servers at this hosting company trip over this statement, those at another, where I have other sites hosted, had no problem with it!

Working with the tech support guys and referencing this getK2 Forum post, we were able to fix it!

From the earlier post (12 months ago!)

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);
