杂志要求图片单独上传，要求是：“Upload each figure as a separate file in either .tiff or .eps format, with the lead author's name, the figure number and the top of the figure indicated. Compound figures e.g. 1a, b, c should be uploaded as one figure. Tints are not acceptable. ”进行上传操作时，首先我的文件名怎么写（我把作者名字写到文件名上，被编辑退了回来说不对）？上传网站对图片有caption/Legend 和link text两块要填的内容，请问我分别应该填什么？其次，我对Figure 2(a) 和 Figure 2(b)应该怎么操作？大家能不能给个例子说明，感谢！
