Thanks,
Let me know also if you do accept custom plugin development and how to get in touch for this.

So i now only changed this line to replace site_url with home_url and it worked (In file WatermarkPreview.php) and images are showing in the preview. site_url will always include the subfolder while home_url will not include the subfolder wordpress

return add_query_arg( $args, home_url( $base ) );

Hi,
after some analysis, this look like the 404 error because i am having wordpress core files in sub directory (wordpress) https://localhost.youtagon.com/wordpress/easy-watermark-preview/image-6206-large?t=1613680930529
but the preview url rewrite will work correctly if i removed this subdirectory

so using the below url will correctly result in the preview image
https://localhost.youtagon.com/easy-watermark-preview/image-6206-large?t=1613680930529

i am basically have the below folder structure

Giving WordPress Its Own Directory

i hope this help to be able to recommend some fix

Thanks for getting back to me, it is a local development and i am testing the plugin on it
below the message printed on the console
https://localhost.youtagon.com/wordpress/easy-watermark-preview/image-6206-large?t=1613680930529

This is a quick shot of the error, let me know if additional analysis is needed and i can do it
