There are many questions on where to release photos for sale or copyright information. I have taken some photos that are not world class, but I think useful for some people. I have been working on a section on my website with resources for people. So far I have been creating tutorials and releasing 3d Models. For tutorials it is easy for others to find because the content is written and easily searchable. For models, releasing them on thingiverse works somewhat well.
Is there a common announcement board or site that I can let others know about the free photos and the repository that I am making?
