In fact, most of the source maps of articles published in foreign journals can only be seen in articles, unless you ask the author for them.
In a few papers, you can click on the picture to link to the source picture. At present, only a few journals have this situation. There are two ways to find the source picture.
1, ask the editor or the original author for the author's original file, which will contain moving pictures.
2. Some papers have supporting information at the end of the paper. If there is such a SI, it will generally be explained in the article. Downloading this SI in the log may result in moving pictures.
