I need to have my content folder at ../../www/gallery/ (meaning relative from the ImageVueX dir). How to do this?
You mean you want your contentfolder outside the Imagevue folder?
If your Imagevue folder is at "site.com/imagevue/" and your contentfolder is at "site.com/content/", you could set in config:
contentfolder = ../content/
or in URL parameter:
?contentfolder=../content/
As you can see, relative to main Imagevue folder. However, I need to warn you that working with content outside the main Imagevue folder is a little dodgy. We discussed this as of lately, and some servers wont even support this procedure as it is considered 'unsafe' for a script to access files on a parent level. Like most other galleries, we might require any content to be within the main Imagevue folder in future versions.
