Add Image to Blog Entry - Image Gallery is null


I'm working with Community in EPiServer 7.5. I'm trying to add an image to a blog entry. This is the code

  stream.Position = 0;
                    // Create a image and set the presentation name of the user as name of image                                    
                    EPiServer.Community.ImageGallery.Image presentationImage =
                        new EPiServer.Community.ImageGallery.Image(entry.ImageGallery, FileName,
                            FileName, CurrentBlog.Author, stream);

                    // Add the image to the system
                    presentationImage = ImageGalleryHandler.Instance.AddImage(presentationImage);

                    // Set the image to presentation image
                    entry.SetAttributeValue(BlogAttributes.PresentationImage, presentationImage);

But it falls over at 


with a null exception - it looks like the image gallery associated with the blog entry hasn't been created

Can anyone help please

The error is

Value cannot be null.
Parameter name: image.ImageGallery

I can't see how this is created. If I reflect out the dll it should be loaded from the owned object collection

The image gallery can be assigned to directly because it is read only.

Can anyone help?

(PS - Moan - but I'm astonished how difficult it is to add an image to a blog entry. I would have thought this was a really standard requirement for a community tool. Moan over)

Actually I've changed tack with this

Image inserted with the normal images

Content Reference ID stored as an attribute against this blog entry

Image can be retrieved based on that content reference

Forget all notions of image galleries
