Can you do image verification if it loaded on webpage?
Yes! You can verify but you cannot say that images are half loaded. To verify if an image is correct then there would be some other method but the code will tell you just that images are loaded on the page or not.
You can send HTTP request to that source using GET method and check the status code as 200. if that the case then your image downloaded properly and an image is there.
Please drop your comments if you think if I am missing anything. If you have another idea to do image verification, please comment.
