Otherwise,I have used "WebThumbnailViewer1.ViewerID = WebImageViewer1".

So, WebImageViewer1.ImageInfo.Url=="",and,

WebImageViewer1.ImageInfo.CacheFileName=="".

How can I konw the "WebImageViewer1.ImageInfo.Url" from "WebThumbnailViewer1"??

e.g.WebThumbnailViewer1.Add("resources\\temp\\image.jpg",1,1);

Hello,

Neither the WebImageViewer nor the WebThumbnailViewer have the ability themselves to watermark images. This has to be done either by creating annotations over the image to create the illusion of a watermark, or you have to change the image data itself. With the web controls, you would have to change this in the file itself.

I'm attaching a small sample project that illustrates how you could use the combine command with either a watermark image that is generated on the fly, or combine an image from an existing file. This example will decompress the image in the file, and then watermark the image. The image would have to be recompressed out to the hard-drive, and then the file location passed to the viewer for display in the browser.
