I have a list definition that will have a title, description, and a few picture fields. Each entry in the list will represent a project. I do not like to use the SharePoint hyperlink/picture field type so instead I'm using the image upload from Bernado Nguyen-Hoan's Blog. I've got an instance of the list, along with the list definition, that deploys with my visual studio solution. However, when I go to the list to create a new item and I upload the image to my column it throws an error because no library has been specified where I can store the images. The field type is supposed to default to the "Images" library but when I go to edit the column I see that the "Upload Images To" field is blank. How can I set this in my list definition schema.xml/elements.xml files?
