So in the UK, pretty much everything is illegal without getting express consent. Things such as a screenshot of your OS X or Windows desktop and, say, creating one of those PDF icons that uses the Adobe PDF icon.
Well, there are quite a few things that you can do that come under the heading of “fair use” in the UK, but none of them seem to apply to your case. That said, you see screen shots of, say, the Windows desktop all over the place. As far as I know, Microsoft have never objected to this. In the unlikely event that they ever decide to take action, it’s a safe bet that they wouldn’t start suing people wholesale. At the very least, they would announce their change of policy, and give the alleged offenders time to do something about it. But it’s highly unlikely that it would ever come to that.
Do you think it’s reasonable then that whenever using a screenshot just add some small print saying who owns the software, that I am not affiliated with them?
It certainly can’t do any harm. There’s no need to make it too prominent. A simple caption in 9 pt type near the image should be enough.
Take this icon, for example: http://www.iconspedia.com/icon/andro...hop-16-15.html It may be a unique work in that is was created from scratch. However, it clearly resembles the Adobe Photoshop logo. Is that legal?
I would say that particular example wouldn’t be legal in the UK. Nor would many of the others in that collection. The IMDb logo, for example, is clearly the trademark of a commercial entity.
Regarding the other examples you quoted, things like HTML and PHP are sort of open source - I don’t mean that literally, but they are not trademarks of a commercial enterprise, so their licensing is likely to be more permissive. But I’m not sure about that.
To summarise, I would avoid any logo that is obviously a commercial trademark. For the other things you mentioned, you’ll be reasonably safe to go ahead, but be prepared to remove anything in the unlikely event that the copyright owner asks you to do so.
