I have a website that shows galleries, users can upload their own content from the web (by entering a URL) or by uploading a picture from their computer.
I am storing the URL in the database which works fine for the first case but I need to figure out where to store the actual images if a user uploads pictures from their local computer.
Is there any recommendation here or best practice on where should I store these and how can i store it on server?
help me! thank you very much

...It might be an old question. I have recently created a website where the Navbar menus are dynamically generated by category. Inside those categories, different posts are created from the backend. Now the problem is when I change the name of the category, it is obvious that the <li> name in the website will also be updated. But it is not happening. Funny part is, it is changing in the database. I already checked that. When I am stopping my project and re-running it again, then it is working. Can anyone help me out with the problem?
N:B- I am taking my category name data through a global viewbag filter.
This is the code.
