try changing this
img1.ImageUrl="images\\img (1).jpg";
or
img1.ImageUrl=@"images\img (1).jpg";

Instead of using "images/img(1).jpg" use as Server.MapPath("~/images/img(1).jpg");

@Mamta - did you observe the direct path is it eqivalent to the the one you share in the snippet? There is a possibility the path you are making might not be valid. I suggest to compare the direct path to the one you are setting using C#

@Asma yes its exist .
If we directly giving Image path to img in aspx file than its visible and do not throw an error
but when I am trying to assigning from c# its shows an error .

Does your image exist in the bin folder to the designated path?

Please read the following link carefully, may be you can use something like LoadCompleted or PreRender

While I am not an expert on the subject, I suspect that the fact that you are writing the code in Page_Load event the control you are trying to access is not yet loaded at all.

Can you not just do a simple null check first?

if(img1 != null)
img1.ImageUrl = ...

The above will confirm whether control is found or not.
