If you're still interested in checking out this image library (which is now Silverlight 2.0 ready), check out our open source page.

Another quick option to teach yourself the needed syntax to do this is to create a simple Silverlight project in Visual Studio, build it, and then just look at the command-line arguments used by inspecting the "Output" pane.

The Mono release, at best, inches closer to Silverlight support. I gave it a try yesterday. Prior to the release, you had to apply a code patch to the Mono source in order to be able to test Moonlight. Now, you can forego that step, but many steps still remain to buid the (very much unfinished and unreleased) ...

There's no easy way to do this, but you should check out what we've done in fluxify.

No new posts, but he wrote the news about the SaveFileDialog in a comment to his post about the install experience.

We're doing the JPEG decode, resize, and encode all in managed C# client-side. For the preview, we're actually rendering it manually using a bunch of pixel-high Line() segments. I just saw on ScottGu's blog that Silverlight 1.1 final *will* have a SaveFileDialog, which really completes the picture for operating ...

Not sure if you've solved this yet.. but I recommend trying an ASP.net Handler (ashx) rather than an ASP.net page (aspx). That way you don't have to do Response.Clear() and you know more precisely what is getting sent to the client.
In that case, your code will be similar to:
// GetImage.ashx
protected override void ...

I think s/he might be asking for how to take a "screenshot" of a running silverlight application.
If so: Print Screen! Whereas you can snapshot a drawing area in WPF, you currently can't in SL.

// GetImage.ashx
protected override void HandleRequest (HttpContext context)
{
// Process querystring here if you want to let the client have some choice
using (System.Drawing.Image yourImage = GetImageFromDatabase() )

You have to send the image bytes (in some Silverlight-compatible format, such as JPEG or PNG) to your Silverlight application. See the project that I linked previously -- it shows you how to go from a System.Drawing image to a web-accessible ASHX. Once you get this figured out, it is easy to set the "Source" property on ...
