If you mean the background image with the elephant statue that we see on https://www.indianfests.com/ is not loading: this is probably because Android requires all requests to use HTTPS by default from target API level 28 onwards.
The background image, however, is specified as plain HTTP: http://www.indianfests.com/wp-content/uploads/2020/08/wordpress.jpg
. The server immediately redirects it to HTTPS, but because the HTTP request is blocked, the WebView cannot know that (and even if it did, it would be insecure to use it anyway). You can also see this in a regular web browser, which should show some kind of warning text or icon in the address bar.
So the best way to fix this is to simply change the website to use HTTPS throughout.
If you absolutely, positively cannot do that, you can use <application android:usesClearTextTraffic="true">
in your manifest (documentation). But for the security of your users, please consider this a last resort.
