Started posting this as a Comment, but it got away from me, and the formatting of Comments is terrible... so here we go.
Honestly, I'm not sure what all was in the pack ParalumanMod posted. I never bothered to download/access it, because it wasn't relevant to me at the time. I just know that it was supposed to be Art Assets for use in fan created art, YouTube videos, or what have you.
Recently I've been working on some informational things for my guild, which I wanted to "decorate up" some, so that it wasn't quite so plain looking. I may also end up making more of them, if the things I'm working on now prove effective, which I may need reference images for.
That's why I wanted to see what was in the pack, to see if that might be of help, both immediately and in the long run.
I've also considered making some videos, but have been on the fence about that. So I wanted the Assets mentioned in case I did, so that I would be using officially sanctioned and allowed media (if/when needed), rather than accidentally using privately created art that might make someone complain that their personal work is being used without recognition.
That's why I preferred an officially allowed source, just as a "just in case" kind of thing.
For the most part, however, for the thing I'm working on right now I was hoping it had something for use as a background image that was clearly CC related. Either wallpaper type things, maps/map backgrounds, Hero group images, buildings and things like that. Something I could build a proper background image out of, if it isn't already ready made.
For instance, if there is an archive of the various backgrounds used on this forum or the numerous loading screens used for the game itself, that would likely be fantastic for the purposes I need at the moment, if those are a possibility.
Overall, however, I'm not sure what exactly I'm looking for, just have a general idea to lead me around a bit.
Also, thanks for that link. It's not exactly what I was looking for, but may be useful in the future, if I continue making info stuff for my guild.
