Just wondering, did you ever try the 1k chunks or TransmitFile() methods as suggested in earlier comments? Cheers Andy Hi,

That way you dont have to bother using the ImageStream and the Image object. context.Response.TransmitFile(fileName); context.Response.End(); Did you test the built in function in ASP.NET to transmit files?

context.Response.TransmitFile(fileName);
context.Response.End();

I'll fix the example to read 1K chunks and post immediately. I think asp.net will buffer automatically anyway so that would be better. I'm on vacation this week, but will do it next and post the results. -Peter Kellner Good point. I’ll fix the example to read 1K chunks and post immediately.

This will be much faster and incur almost non memory overhead. Your example loads the entire graphic into memory, and if it was a 1GB zip or bmp even, it would surely kill most servers. Not to mention you can add a isClientConnected for insurance. Try reading the bitmap in 1024 byte blocks and stream it out as it’s read in.
