The CRMAttachmentImage control downloads on codeplex have been updated to include gif and webcam support that I talk about in a new article that includes some instructions that may be helpful.
A while back Christian asked about this image control I had in a screenshot on one of my posts. And while it was ok, it was far from being something I would throw into a production environment. It was a starting point. I am proud to say that I have put the Silverlight control on codeplex at CRMAttachmentImage.CodePlex.com. It is in beta because I am still working on putting the buttons on the ribbon instead of in the control.
The image itself is stored as an attachment in the notes. This way the control is utilizing CRM and not an external system to handle the images. Simply put in order to use this your users will need to be able to read notes and create them. They will also need the "Customization > ISV Extensions" permission. If you are not seeing the images, and everything else is right, then try checking the permissions.
Instructions are posted on the codeplex site, but it is fairly straight forward to add to a form. First, you just upload the web-resource and create a text field to store the guid for the not (annotationid). It MUST BE ON THE FORM, but it does not need to be visible, and you probably don’t want to make it searchable. The web resource does require the id and type to be passed, and some additional parameters.
The parameters are separated by a pipe | instead of a comma. An example parameter is:
