I'm not sure if vendors get a message or not, but I have had vendors post comments on my images. Some, which I'm 'friends' with after I contacted them to let them know an image is up, but also some have posted remarks without me informing them that I posted an image..... that's in the Vue gallery section, but using poser products in my Vue images. I'm sure there are vendors who are active in the galleries, I'm a vendor and I post comments in the galleries.

Think of it this way, seeing the many images posted each day, it takes a lot of time to keep track and posting comments and all that time is lost making content. Personally, I've stopped visiting the Poser galleries, there are only few images there that interest me, I've seen enough naked or hardly clothed 3D models. I do visit other galleries though and post comments on the artwork.

But if someone gives a vendor credit and the vendor would get notified somehow, I think they should post a comment. But if they do not get notified, it's hard to know. Perhaps someone else knows if vendors do get a email message from Rendo telling them someone credited their items in an artwork.

Personally I don't always credit every vendor, I do it the first couple of times, but after that I hardly do. Sometimes there's so much stuff in my images, that I don't even know who made what.

Artwork and 3DToons items, create the perfect place for you toon and other figures!

Due to the childish TOS changes, I'm not allowed to link to my other products outside of Rendo anymore :(

Food for thought.....
