I'm trying to point the location of an image in the cloud (Dropbox) using TeX on Mac OS. The problem is that I require full path name which contains the username (different for both machines). For example the path on machine 1 is:
/Users/user_name1/Dropbox/image.pdf and on the machine 2 it's
/Users/user_name2/Dropbox/image.pdf. In such case, I would have to change the path whenever I'm changing the machine (user) to be able to compile the document.
Is there any way to shorten the path name so that I can point to the files universally on a different machines?
