ID: Nobody follows this rule, so I would have no idea which number were up to
Airline: Many foreseeable airlines
Problem: Logo gets accidentally replaced.
Technical Details: Logo is written over if same name found. For example, Untitled.jpg, if shared amongst two airlines, will be replaced.
Solution: Get Air El to replace logo name with ID number so as to NOT get overwritten logos. Simple script really. Except you'd need everyone to redonate their logos again
