No, it is not saved because of different reasons, I faced the same problem once, and after wasting hours, I found that it was a security issue, actually, the directory where I was uploading the images had only read permission.  solution:-  open the file manager in IIS and go to the directory and change permission from read-only to read and write.

Sachin Singh Thanks for the reply , I have run the project in visual studio everything works fine the same project i deployed on IIS using published version I put my project in D :/ EvaluationSystem
now when I go to edit my students the URL is localhost/STudent/Edit/1023 and it says 404 Error , when I add the Directory name in front of it like localhost/ EvaluationSystem /STudent/Edit/1023   it works so what is the issue Do i need to append the directory name with all of my controller?

Hi,Please check if studentPhotos folder is present in your published folder or not (Which you have deployed on IIS). If not please create the folder with a specific name and add proper permissions and try.
