Let's say that i have a image
restaurant-photo_big.jpg which is 640x480..
How can I change the resolution safely for SEO purposes? it's the same identical image but 800x800 (it may be cropped out compared to the old one).
- Should I simply replace
- Should I leave on my server old
restaurant-photo_big.jpg(not linked anywhere) and create
- Should I 301 redirect
thank you in advance :)
