Generate Dynamic Images Using ASP

[telicasp]

would be great if someone can help here...

An admin person logs in to a HTML calendar and clicks on certain dates,
the dates clicked by him gets highlighted and changes to a different color.
(here the TD color is changed during onClick)

NOW, I would like to EXPORT this to a JPEG or GIF Image.
(note: The exported Image would contain the dates selected by the admin )

Is this possible using ASP / SQL SERVER without any third-party component being installed. I cannot use any componenthere, bcoz of the server restrictions...

This has got to be possible. I have never done it, but I know what I would try. A gif file is just a long line of bytes like this:

totalBytes = "71, 73, 70, 56, 57, 97, 15, 0, 15, 0, " &_
   "128, 0, 0, 255, 255, 255, 0, 0, 0, 44, 0, 0, 0, " &_
   "0, 15, 0, 15, 0, 0, 2, 33, 132, 127, 161, 200, " &_
   "185, 205, 84, 128, 241, 81, 35, 175, 155, 26, " &_
   "228, 254, 105, 33, 102, 121, 165, 201, 145, 169, " &_
   "154, 142, 172, 116, 162, 240, 90, 197, 5, 0, 59"
bytes = split(totalBytes, ", ")
for each x in bytes
   response.binaryWrite bytes(x)
next

The only tricky thing is the binary write line (I don't think that will really work) But the real question is how do you write this as a binary file? Using fso you can easily write text streams, right? There should be some component comparable to openTextFile. Maybe openBinaryFile? I've just never heard it discussed.
