I have put into my paper a photo (available here) that I have collected from the company's website available for free. There is no copyright note, except the one at the bottom of the website and product is available for sale (probably patented). I have contacted the company seeking permission, but they did not reply after a week and I cannot wait anymore.
The paper will be published in an IEEE magazine.
So here are my questions:
- How to make sure an online photo carries copyright?
- Is citing to their website sufficient to avoid copyright violation?
- If received copyright permission, how to use the permission in the paper? (I received permission from another company for another photo). Write it on the image or write "courtesy of ..." (I have seen this phrase quite a lot).
UPDATE 1: Thanks all of you, referring to your answers, I decided to stay in the safe side by removing the photo from the paper. I did not criticize anything and did not admire it either (but it could be a free publicity for them which is ignored despite second email to the company). I just discussed its functionality as an encouraging innovation for particular domain.
However, almost NO ONE yet commented on 3rd question. Can any one help in this regard?
