It is possible to have Djuggler to wait for an image on a web page (or other window), and click it if appears, or do something else if it doesn't?

If the image has a unique name or specific place in a web page you could do that with a construction like:

- loop range 10
. wait 2000 ms
. find text from position
. if text found then
.. set variable foundimage to Yes
. exit loop
. End if
- end loop

- If foundimage equal to yes
....
- Else
....
- End if

This construction loops 10 times with a wait of 2 seconds in the loop. When the image is not found in 20 seconds it will do something else.
