Can I used an ASCII generated version of a copyrighted image in my game? I'm going to guess the likely answer is no, but I'm interested to know more. So let's say I have an image of James Bond from Goldeneye. Then let's say I run it through ASCII art generator such as this http://picascii.com/ and it produces the following ASCII code made for the web as such (can't post here but here is a JSFiddle of the generated code). https://jsfiddle.net/caimen/ope1j9w0/ Why or why would I not be allowed to use this version of a copyrighted image in my game?
The reason is 17 USC 106: the owner of copyright under this title has the exclusive rights to do and to authorize any of the following... (2) to prepare derivative works based upon the copyrighted work The original picture is the underlying protected work. The ASCII reproduction is a derivative work. If you get permission to make the derivative work, it is okay. Otherwise, it is copyright infringement. There is an escape clause, "fair use", which amounts to taking a chance that you won't be sued and then arguing that you didn't do them any prohibited harm. If you make any money off of the game, you have a major strike against you. I suggest reading the fair use FAQ; basically, it is really hard to know how a fair use defense will fare, but based on prior cases, I'd say it's infringement, not fair use.
It would seem that your song is a derived work. You took the original work and found words that sound the same. If the original work had used different words, your work would have ended up differently. So you have a derived work. Same as making a translation; if the original was different, then the translation would be different, so the translation is a derived work. I was asked "How is this not straight up infringement". But it is. Not only copying is an exclusive right of the copyright holder, but also the creation of derivative works.
A matter of terminology, what you want is not the copyright, but a license to use the copyright, presumably a non-exclusive license. You would probably need to approach a licensing department at Disney. They will ask lots of questions, and if they are open to the possibility, will quote a fee, which will, i would think, be sizable. Anyone should be able to ask, but I suspect that most requests are refused. It would probably be well to have a business plan laid out, and exactly how the images would be used in your plan. Disney can refuse any license, or offer one on whatever terms it pleases.
This would likely be considered a derivative work. You would need permission from the copyright holder to make it, especially if you intend to distribute it for profit.
Such an image is copyrighted, as part of the movie. You cannot legally use it without permission from the copyright holder, unless the use of the image falls under fair use (note that fair use is a strictly US legal concept. It does not apply anywhere else) or a similar exception to copyright, such as "fair dealing". There are multiple factors which must be considered in making a fair use judgement. No one factor ever totally controls the decision. It is a case-by-case decision. But several things about your proposed use suggest to me that it will not qualify as a fair use. The image is part of a creative work, not a work of non-fiction such as a news report or a textbook. That weighs against fair use. You seem to be using the whole image, although it is only part of the movie. That probably weighs against fair use to some extent. A use in "a social media post regarding a sales vacancy" sounds commercial to me. If so, that would weigh against fair use. The copyright owner might well wish to market images from the film. If so, and if many people used images from the film as you propose to use this one, that might harm the market. This weighs against fair use. You don't seem to be making any comment on the image, or using it in any significantly transformational way. That weighs against fair use. Use of the image does not seem vital or even important to the message you intend to communicate. That also weighs against fair use. In short, I think you would be wiser to use an image that you have or can get permission to use in this way. If you use this image, it is possible that the copyright holder would sue for copyright infringement, or issue a DMCA take-down notice, or both.
Probably not, without permission. Images of the character are usually copyrighted. The characters themselves are usually protected by trademark. Using the name of a fictional character without permission would imply endorsement by the firm that published works with that character. I've taken day long seminars focused mostly on all of the things that comic book companies do to protect their intellectual property rights in their characters. Of course, if you live in Finland, it is likely that no one in the U.S. would decide to take up the case for a U.S. media property, either because they aren't aware of it, or because it isn't economically worthwhile to pursue.
In general, the output of a program is not copyrighted by the author of the program. When you write a novel in Word, Microsoft doesn't own any copyright in your novel. When you prepare financial statements with Excel, Microsoft doesn't own any copyright in those either. There can be exceptions. Some programs (like GNU Bison, a parser generator) actually do output parts of their own source code, and their source code is copyright to the author. To clarify things, GNU made a statement in the license for Bison that officially says they don't have copyright to what it outputs. You should expect programs of this type to have such an exception, and if they don't, maybe ask the author or don't use them.
You probably can. There are a few questions here. First, is the message protected by copyright? In general, it probably is, but there are many exceptions that might allow you to use it without permission. Unfortunately, these exceptions vary from jurisdiction to jurisdiction. The exceptions tend to allow the use of small excerpts of a work for various sorts of purposes that don't undermine the copyright holder's ability to profit. That leads to the second question, which is why you are using that message. If you're including it in your source code so you can test whether a message generated at run time is in fact that message, that's one thing, and it's probably okay. On the other hand, if the owner of the copyright sells a database of all its message strings, and you're compiling a similar database that you also intend to sell, that's probably not okay. A third question concerns the Firefox license terms. It's entirely possible that they allow you explicitly to do what you're considering, in which case it doesn't matter what copyright law says about it. On the other hand, Firefox is open source software, and under some open source licenses, if you incorporate any of the source code in your own product, you are required to release your product's source code under the same license. If you're not already planning to do that, you should consider carefully whether including that error message would trigger that provision (if there is one) of Firefox's open source license.
