Upload & Sell: On
You always retain the copyright ... but the contract that you agreed to may have terms in it that preclude you from using it / licensing it elsewhere, so review the contract that you agreed to.
Given the ToA @ Facebook (other social media, Flickr, etc.) debacle @ you post it they (or others) can use it ... it could be an opportunity for some grief down the road as you would then be giving unlimited opportunity for others (per your ToA) to use it (after your agreement with the publisher), which could be counter to your agreed upon usage/licensing contract with the publisher depending on what is included in that contract.
But, if you are providing the link to the publication and sharing it in that manner, I see that as free advertising for the publisher, with you not making the image available to anyone else. I'd say "link away" till the cows come home ... but double check your contract before posting up the image in social media (which has its own debatable perils in general anyway).
Original image in social media (ToA to everyone) ... Run Forest, Run ... Danger, Will Robinson.
In the vein of an old school "tear sheet", maybe something like this:
Might be easiest just to ask in writing (email, etc.) the publisher how they would like for you to proceed with marketing your work/their publication. Then, when you get something from them in writing, you've CYA'd yourself and expressed professional concern for their interests as well.
That's my .02.
BTW ... Congrats !!!
Now, where's our link.
