I purchased Simple Image Gallery Pro. Now, at least it shows up as installed.

I set the proper upload path - media/k2/galleries/
I set "slimbox by MooTools"

It all seems to work except that the thumbs don't show in the front end. If you click on a blank thumb then the full size image will show. Instead of a thumb, I seeing this image in its place:
plugins/content/jw_sigpro/sigpro.transparent.gif

Check the image names - no spaces, (brackets), special characters.
Check the zip archive for unedited image files - or un-optimised images.

Had a similar problem - a combination of unsafe file names and ONE image that had not been edited by client, but uploaded anyway.

I've also found it easier/more effective to edit the file names on the server via FTP rather than try re-uploading the zip archive.

HTH

Thanks Mark. That was it. There were apostrophies in the file names. I removed them on the server and the issue is fixed.
Thanks for you help.
