Hi,

here 'm proving some code for generating capthca image.

By using this code we can generate capthca image.So,we can load new capthca image when ever we want.If you place generate code in pageload with in below if condition .The capthca image loads only once at pageload not in postback

C#

 if(!IsPostBack)
{
   //place captcha generation code or call that method
}

I hope you understood what I said.

All the Best

So ,on every pageloads the asp control rendered and generate new image

upto my knowledge the best way is generate images by code is better than any other way b'coz we can control .

check in net for stopping rendering process of control in asp.net

saving image in database is not good idea in my view.
save that image in particular user folder and
store that path in DB table column which is belonging to that user.
on user logon store that path in session["profimgpath"]

then you can use whenever you want

try some code for this

if any error come back with error
all the best
