I am now in panic. One of my paper got accepted by journal. However, I am stuck with the copyright from two figures I have used in my research paper. These two figures ( these two from open access internet source and free to the public). I just simply thought that I will acknowledge/reference their organizations in my paper and that's it. After I read the copyright requirements from journal, I realize that I need to write and ask for permission from third parties. I already write emails to them but it might take a long time or even they don't answer my email. In there website, it is said that :"All materials that appear on ADB's official website, adb.org, are its exclusive property unless otherwise indicated. ADB encourages users to print, download, or copy information, documents and materials from the website exclusively for personal and non-commercial use".
my research paper is now in the production stage ( pass all review processes) and needs the last step of proofreading.
Is there any chance that I remove these two figures from my accepted manuscript? Or what should I do now.
I know it's my mistake and this one is my first research paper, I don't have any experience in publication. Please help me , I really appreciated for your advice.
