I am trying to use the Designit Gallery Package and need to ask a couple of questions about how to implement it. I have created a document type called Gallery and have added the media picker. I have created a template called Gallery and included the macro as follows
Now I added this exactly as shown on the codeplex site, apart from changing the dimensions, and I am unsure what the value for 'folderId="[#Gallery]"' relates to?
I can create a Gallery page under content and it allows me to navigate to the media folders. I pick a folder, called images for example, but none of the pictures that are inside of that folder get displayed however I do not get any errors either. Any idea of what I have missed?
The plot thickens, I tried changing folderId="[#Gallery]" to be folderId="1094" where 1094 is the id of an image folder under media. Now I get the following error
Object reference not set to an instance of an object.

Eveything is where it should be as far as i can see.
In case you are still trying... I had the same problem today on my first Umbraco project!
My issue came down to not having my html <head> tag running as a server-side object.
I needed to add id="head1" runat="server" and that solved this problem.
This is due to the code for the gallery adding lightbox scripts to the page header. If the header doesn't exist server-side, then it returns a null reference.

Hello Andy,
In case you are still trying... I had the same problem today on my first Umbraco project!
My issue came down to not having my html <head> tag running as a server-side object.
I needed to add id="head1" runat="server" and that solved this problem.
This is due to the code for the gallery adding lightbox scripts to the page header. If the header doesn't exist server-side, then it returns a null reference.
All the best
