It is interesting to learn about creative commons as a tool.I have been using google images for a long time and frankly never though about the copyrights but this task taught me the importance of using creative commons.
I looked for Digital age in the flicker in creative commons and this is what I get. Every picture has some kind of right attached to it.
And the same search in google images tells us ‘ the image may be copyrighted’.
Although i still need to actually explore it for my usage, so its too early to comment on it.
