That's interesting, because the code did not contain that statement, as the
site suggested it should.
And it worked except for the crazy filename in the dialog box.
Do you think the context.Response.ContentType = "image/jpeg" line caused the
dialog box to open?
I see in the code lines like:
zz=context.Request.QueryString("Size")
So, just to see, I tried:
Dim s As String = context.Request.QueryString("Filename")
which of course doesn't work.
Am I close?
Is there something that does work to get the filename?
Thanks for the info
