graphic asset library?
I am trying to establish a graphic asset library for our course development. We have a few assets, but not enough for a fully functional development role. I was thinking to look at a couple of online graphic sites i.e. fotolia, shutterstock, dreamstime etc. Are there perhaps other ones that any of you are using? I do have a limited budget. I'd like to have great usage out of it. Any recommendations will be greatly appreciated. Thanks
