Considering what he promised you, the least he could do is allow identifying which images are yours. 
  It is not uncommon for initials to appear on species illustrations (but also not uncommon for them 
ot be removed in the old days by authors and publishers), but rather uncommon for standard graphical 
content like charts and graphs to have initials (but sometimes the artist is mentioned in the caption.)

You do have a written (email) agreement that you have traded something of value (foregoing money) in 
return for authorship acknowledgment.  You can not let this slide. You should email him and nicely 
remind him of the agreement and what you agreed to do for him for no money.  It maybe that he has 
indeed just forgotten about it. Or there may be other issued stopping him. Either way it needs to be 
address. Either he has to pay you the money you did not get, offer you some other consideration, or 
at least apologize profusely and make you as prominent as you can be in the article without being an 
author.
