Hi,
This plugin was working okay (not great, but okay) until a few days ago when a user called me up to say it the page displaying the gallery was showing a bunch of errors such as:

"Warning: touch() [function.touch]: Utime failed: Permission denied in .../plugins/content/jwsigpro/sigpro_engine.php on line 41

What is causing this?  How can I fix it?  I've tried everything!  please help!

Here is an example: www.harvestingjustice.org/index.php/immigration-labor-rights/120-support-indian-citizens-victimized-by-us-guestworker-program

*edit* nevermind. I have uninstalled this component.  I gotta find something that works.

Permissions conflict...

Just comment out the line 41, at sigpro_engine.php
if you don't want to modify the permissions on general joomla standards.

Thank you!

I think this is what caused the thumbnails to stop working!  I just realized the connection!  I commented out those lines and the errors went away but the thumbnails stopped working.  Why? 

*edit* well, no, maybe not.  I undid the change (uncommented out those lines) and the errors came back but still no thumbnails.  fudge.  thought I'd solved the mystery of the missing thumbnails.
