+### Crafted/fuzzed images
+
+Images that are create by fuzzing or specially crafted to trigger some error
+conditions should be added to the directory *fuzz-tests/images*, accompanied by
+a textual description of the source (bugzilla, mail), the reporter, brief
+description of the problem or the stack trace.
+
+If you have a fix for the problem, please submit it prior to the test image, so
+the fuzz tests always succeed when run on random checked out. This helps
+bisectability.
