I made a David Bowie Magazine for school and want to present it on my homepage. I couldn't find any free-to-use images online, so I just took some from google images.
I thought about removing the pictures for the online-version and all the texts and replace them with a filler text but that doesn't work, e.g. on my cover I have a black/white picture with Bowies face. I can't replace it with just black.
How can I make my magazine legal for the internet? More specific: How should I edit my photos so that I can post my magazine on my website.
