Images corrupted after uploading images in Admin panel

When i tried to save the products at first by entering the urls of the products I got a operational error so then i uninstalled django 2.1 and then installed the latest version of django. Everything was running perfect until i used the bootstraps to make my /products page. All the texts were working fine but my images were not loading properly . Then i went to the admin panel and changed the urls but it was the same. Then i noticed that my images get corrupted after pasting the urls of the products and saving them. The images were good before saving but after saving the images get corrupted.
Any Help much appeciated!
