findSomething = wait(<image_screenshot> ,10)
if (findSomething):
	popup("foundddddddd")
else:
	popup("nada")


I am using the wait(image,timeout) to find whether an image exists in a given page. The script works if it can find the image, however, if the image doesn't exist I get the following error:

at org.sikuli.script.Region.handleFindFailed(Region.java:349)  at org.sikuli.script.Region.wait(Region.java:420)  at org.python.proxies.sikuli.Region$Region$1.super__wait(Unknown Source)  at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)  at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)  at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)  at java.lang.reflect.Method.invoke(Method.java:597)  org.sikuli.script.FindFailed: FindFailed: can not find ADDTDCA

Any idea what might be happening here and how to fix it?
I need it to display "nada" if the image doesn't exist.
