How to change image address for other domains?

Question

htaccess

Here is an example. There is a site, there is a logo in PNG format - white with transparent. Due to the background image, it is clearly visible, and if you specify a link to the site in a contact (for example), it catches this image, but white on white is not visible. There is another version of the logo with a background, but the style of the site is not very suitable.
Let's say the image is located at 'mysite.ru/images/logo.png', is it possible to get another image for external requests at this address?
I'm thinking of doing it via .htaccess, but haven't figured out how yet.

Answer 1

make it in svg
This is an open format, it is inserted directly into the layout, it is easy to read, and coroldrow can immediately save the style sheet to it in css. And then they finished the php logic.
