System.Byte[]

Dim imageBytes As Byte() = DirectCast(sdr(2), Byte())
context.Response.BinaryWrite(imageBytes)

• You should wrap the SqlDataReader in a Using block.
• You don't need to check sdr.HasRows before calling the sdr.Read() method.
• Since you're only returning one record, you can replace the While sdr.Read() ... End While block with an If sdr.Read() Then ... End If block.
• You should probably set the status code to 404 if you don't find an image to return.
• I'm not sure what you're doing with the ArrayList variable; you seem to store things in it, but never use it. You also have an unused DataSet variable at the top of your method.
