Thank you for reaching us here at Judge.me forum.
I'm afraid that is not possible to upload product images only for social media, since the image data is being picked from your product.
We hope this clarified your concern and feel free to reach us at email@example.com if you have any further questions.

When reviews are posted, it will often use the product picture from my website. However, that picture is sized for my website and not properly sized for social media. Is it possible to upload product images that will be sized correctly for social media? I don't want to change my website pictures... I want to upload some different-sized photos, and you can use them when you need to share a review on social media.
