I put up a demo of FreeTextBox 3.0's image gallery control (it's the image button on the last toolbar). You can:
- navigate up and down directories
- set all major image properites
- upload images
- create folders
The main property you need to set it is FreeTextBox.ImageGalleryPath. It uses .NET notation, so “/images“, “images“, and “~/images“ may all point to different places. Please read up on ResolveUrl().
The other property is ImageGalleryUrl which tells FTB where the file ftb.imagegallery.aspx resides. It defaults to “ftb.imagegallery.aspx?rid={0}&cid={0}“. The {0} are replaced by ImageGalleryPath on the client side.
