Please credit, link, and tell me when you've used my stock Link back to the stock photo you used or to my stock account main page in the description of your piece (artist's comment section). Send a note (to this account) with a link to your finished piece so I can see and praise your work.
Use my stock photos for art purposes only Nothing pornographic, hate-related, illegal, commercial...etc.
I'm not sure what you said. Usually I prefer people to ask before posting art with my stock outside of deviantArt, but it looks like you're only sharing on Facebook so that is alright. I would like some credit for my stock photography though; can you "tag" my Facebook page in the pictures where you used my stock: my page is facebook.com/sophiaazhou.sometimesartist
if you're simply displaying it in your portfolio, I'm perfectly fine with it. if the portfolio is online, please send me a link so I can share it in my Permissions List; I like doing a bit of advertising for artists who use my stock.
Of course you may reference! And you should also be able to share/display it on your facebook page as well. If it offends me then you'll have to remove it, but I don't think you will have anything to worry about.
