It's odd to me that the usual terminology would not be pressed into service. If you're following somebody, or a group, they are your
leader or, as a group, leaders.
Alternatively, and because a leader must first be a servant to be a leader, the leader or leaders are your
servant or, as a group, servants.
These are such well known terms, it's somewhat silly to cite the dictionary, but
3. a. One who guides others in action or opinion; one who takes the lead in any business, enterprise, or movement; one who is ‘followed’ ....
["leader, n.1". OED Online. December 2015. Oxford University Press. http://www.oed.com/view/Entry/106597?rskey=z2iWj2&result=1&isAdvanced=false (accessed January 12, 2016).]
The use of 'servant' is more obscure, and requires insight to observe. However, the closest dictionary sense to the idea expressed is
d. your ... servant: one of the customary modes of subscribing a letter, or of addressing a patron in the dedication of a book. †(your) servant: a mode of expressing submission to another's opinion, often equivalent to ‘there is nothing more to be said upon the subject’; a form of greeting or leave-taking.

Or, more obscurely, but expressing the same idea, the Catholic religious sense:
c. With religious signification. Servant of the servants of God (servus servorum Dei): a title assumed by the Popes (first by Gregory the Great).
'Servant' may be a hard sell, but I see no reason 'leader' should be.
So, these might work best:
- leaders or servants;
- leader or servant;
- signposts (the leader's or servant's photos).
If you have objections to 'leader' and 'servant', and if you don't mind looking forward to the unfamiliar past instead, you have a nice selection of obscure, rare and obsolete terms, as well as some that may be familiar in other contexts.
If you dispense with the familiar terms out of hand, you reject these:
The less familiar, obsolete and rare could be revived for use with new senses for new technology:
† way-witter n. Obs. (with pl. concord) people who have knowledge or skill in finding or following paths, routes, etc., collectively ....
["way, n.1 and int.1". OED Online. December 2015. Oxford University Press. http://www.oed.com/view/Entry/226469 (accessed January 12, 2016).]
5. A person who or thing which leads, directs, or conducts (to a place); a guide. Now rare.
["convoy, n.". OED Online. December 2015. Oxford University Press. http://www.oed.com/view/Entry/40890 (accessed January 12, 2016).]
A leader, conductor.
["† duistre, n.". OED Online. December 2015. Oxford University Press. http://www.oed.com/view/Entry/58288 (accessed January 12, 2016).]
your servant, JEL
