Image Use & Copyright Attribution
I am creating an online course for a client and I have sourced all the images I require. I have a range of iStock and Pixabay images which I will provide attribution to in a Credits section of the course. However, I have two images which I am unsure of in terms of the use and attribution. One if from a medical journal (which is the only place I can find it). I have a reference for this image, is it okay to use this image for a client once it has been attributed correctly?
Secondly, I have two Body Mass Index images. I also have references for these images (one is from the WHO and another is from scholarly literature. Again, is it okay to use both these images as long as I provide attribution? I am just unsure as this course will be for commercial use for a client.
I have attached a PDF showing the images and references. I would appreciate some guidance on this or if anyone else could share their experience of copyright attribution as there are so many rules surrounding attribution of images.
