explore and codebehind. it looks to me every input param contains correct value(such as the uploaded image file name, contentType and etc). well, for the imgbin its input param value returns something like "byte[] imgbin={Length=516}". Below is my code, could anyone help to point out what did I do wrong?
Thank you.

}Are you saying you don't get an exception and there row isn't inserted? BTW Don't prefix your procs with "sp_" its bad for perf' they're really reserved for "system procedure".
