Answer 1

This blog post contains code for down- and uploading list items. The rest of your question is really not SharePoint related at all, try that at a Silverlight forum.

Hi ally,

1)Get a photo from the Picture Library or Folder

You can refer the below code to get the picture url in picture library:

            using (SPSite site = new SPSite("http://spsv"))
            {

                SPWeb web = site.RootWeb;

                SPList list = web.Lists["MyPicture"];

                SPListItem item = list.GetItemById(1);

                Console.WriteLine(item.Url);

                Console.ReadKey();
            }

2) Draw text or i want to write text on multiple position in the image .

Please go to Silverlight forum for more help:

 3) Save it back to the Picture Library

Below is code sample to upload a picture to picture library:

using (var site = new SPSite("http://localhost"))
    {
        using (SPWeb web = site.OpenWeb())
        {
            SPPictureLibrary pics = (SPPictureLibrary)web.Lists["MyPictureLibrary"];
 
            foreach (UploadedFile file in RadUpload1.UploadedFiles)
            {
                using (Stream fs = file.InputStream)
                {
                    pics.RootFolder.Files.Add(file.GetName(), fs);
                }
            }
 
        }
    }

Thanks,
Simon
