how to get image url in wordpress without any prefix?

For the wordpress website, I am storing the images to a external server. I have successfully stored the path of the image to wordpress database.

Now, how do i call the images, using wp_get_attachment_image_src function, i’m getting the url with prefix.

like, https://backslashinfotech.in/tropicanamap/wp-content/uploads/https://www.backslashinfotech.in/tropicanaapp/images/house-designers-233.jpg

How do i only get the url without any prefix?

Thanks,
