it depends on your texinputs variable: 

\setupexternalfigures[location={local,global,default}]

here, default will eventually fall back to tex's input path search 

\externalfigure[tmp/cow.pdf]

but, there need to be a tmp path relative to one of the paths that make up texinputs; in context mkiv we can use more clever methods because there we will have more control over finding and opening files; for now, we depend on what tex and kpse/web2c provide
