How to save pictures to a graphic's attribute(which is a Raster field) in editing?

[wangzhifang]

Hi guys, is there a possibility for user to upload a picture file and save it as a feature's attribute in arcgis api for silverlight?
Supposing there is a "photo" field which type is raster in my featureclass, how to save a picture file into this field of a newly created graphic and post it back to the server?
btw, I'm using arcgis server 10.
Thanks for any advice.

I can't find anyway to store a picture to raster field.
You can try to use attachment. Attach any Object(word, excel, picture ...etc.).
It's worked and show in silverlihgt application.

As shryu mentions, this is what attachments were made for.

Hi,

I would like to do the same thing, but your suggestion of using an attachment would require a lot of work. In that case, i would have to write a service which could handle the attachment, and then make the necessary edits through the ArcGIS server SDK on the server-side.

I would like to use an object in the silverlight API to do this. I see in the ArcGIS Mobile Client SDK, there is an object for doing exactly that: http://help.arcgis.com/en/arcgismobile/10.0/apis/ArcGISMobile/WinApp/ESRI.ArcGIS.Mobile.Client~ESRI....

I have looked at the REST API and noticed there is no possibility to pass an image when making a feature attribute edit. This would seem to tell me that there is no possibility to do this through the silverlight sdk. As far as I understand the silverlight sdk communicates to ArcGIS server only through the REST API.

Is there any possibility directly via the silverlight sdk?

Thanks,
Jamie
