OT Mostly - copyright ? regarding translating

Does anyone know what the rules are with regard to copyright and
translations? Does anyone know where I can find out?
For example: if I translate a published piece into another language and
quote the source and don't use the photos can I use the translation? Not
for resale or profit, but just to inform others who are not able to read
the original language?
Any help is appreciated.
