Understandable! I certainly hope I didn't make it sound like I was trying to dispute that! I'm an artist myself so I'm on board aha. It's more a question of if a link to a petsite account can be considered a credit in this instance (a friend told me they've seen it done, I felt it wasn't significant enough, so I'm at an impasse aha), and if Toyhou.se considers their image rules to apply to any art shown on the website even in PM or somesuch. I certainly intend to keep the uploading of any of these images to a minimum where I can't find a Deviantart or something to associate them with, there's just a few favourites I'd prefer not to lose if a petsite profile would be considered acceptable for now (I still hope to track the artists down elsewhere, of course).
(As an example, I have a piece drawn by one of the website artists for Wajas.com when we were friends as kids, which I feel quite sure they would be comfortable with me displaying, but have no gallery link to credit to them. As they are an actual artist for that website I personally feel comfortable linking to their profile there as a credit, but I don't want to assume this would be fine with anyone else, or skirt any rules).
Sorry if that sounds like I'm reading too much into what you said! I very much appreciate the comment I just want to be clear for anyone else who reads this as well aha. Please don't feel like you have to respond as if that was all directed at you.
Anyway, I did see that thread, and once I can be sure of what I can't find on my own (so much reverse image searching to be done!) I will certainly check it out! I feel anxious at the idea of having to bother anyone with this silly stuff, it seems like a solid resource ^^
