It depends on whom or what you’re sharing with or to. The answers that say only share with is correct are outdated.

Use share with when sharing with a person or other entity. Use share to when linking or copying content from one Web source to another Web page.

For example, I would share a graphic with my friends in an email. However, if the graphic is on one web page, I would not share it with my Facebook page; I would share it to my Facebook page.

Since people tend to transfer Internet terminology to other forms of communication, you may eventually hear or see people use share to when presenting information via other media, such as PowerPoint presentations in meetings. I will cringe when they do, but I won’t be surprised.

Bonus:

It is correct to use which instead of what. When the options are limited to a known set, use which. When the options are unknown or unlimited, use what.

It is correct to place a comma after correct.
