Image upload is simple code to understand and execute it. We need to take care of following points :-
– We Need to create Html form with the input type file and submit button
– Form should be enctype=”multipart/form-data”
– Image Validation to check the Image is of Perfect size/type
– We need to check that is image already exist or its the new image
– If the Image is uploaded successfully then we need to show the success message.
