I uploaded the image when I added the new series, "Swallow One's Breath" but now the image is gone and I have added the image twice now over the past two days and it's not showing. I know it's the correct novel cover because I downloaded the image directly from Ridibooks. It's not mature or explicit, so I'm wondering if there is a bug?
while it may be not 'explicit' it could be nsfw (or borderline nsfw) from admin's (or advertiser's) perspective. or it could be dmca'd (not too rare)
It could just be my opinion, but I didn't think the photo was explicit. It's just a woman sitting on a man's lap. His shirt is open and her dress comes down to her upper thigh. There is no cleavage or nip prints. So maybe dmca'd, didn't know that happened!
