When you use TexStudio (iOS), you can drag and drop a figure from finder to the code of TexStudio, then a window of "Insert Graphics" prop out and let you put in the figure with convenience.
However, this function will not include the suffix of my file. e.g. if I add "123.eps", it becomes "123" in LaTex. How can I keep the ".eps"? rather than adding them one by one manually.
It becomes a problem as eps files will fail to be compiled if ".eps" is ignored, and we don't have this problem for pdf etc.
