I am doing research on visual representations in media. I was wondering, is it sufficient if we just acknowledge the publisher's name, page and issue number for each photo? I really hope anybody who had experience about this could share with me.
Mathijs - the original question is about photo images - rather than figures. Photos can't be adapted or 'based-upon'. However, as we are discussing figures as well, authors can say figure 'adapted from...' - but, for safety-sake, it is still best to check with the original author/s. 'Based-on' or 'adapted from' may mean that you've only changed one small detail from the original figure, model, questionnaire, framework etc
Yes, I believe we should - copyright issues are at play here!
And, when you sign the publication agreement with your publisher, there is a clear question about such an issue, and you need to have those approvals ready to support your agreement.
It is good practice to request permission for reproduction, although there are publications that release the rights thereof, with the only requirement to cite the source.
Since you are asking, that suggests a little doubt is in your mind. An old adage: When in doubt don't.
Visit http://www.copyright.com/content/cc3/en/toolbar/getPermission.html . You can determine what is required of you for the resources you wish to use. Fees may or may not be as high as you imagine based upon your use and the number of copies you will distribute.
If you intend to publish your work, yes, you need to ask the permission for the use of the photo. If you do not publish your work, you can acknowledge the photo owner.
@Rahim: Since it is a visual material, you should get the permission from the copyright holder to avoid copyright infringement issues. If it is text, then citation is sufficient no formal permissions required.
