This may have already been discussed here, but I'm too new (and probably too dense) to find the answer.
After having upgraded from 1.7+ to 1.8+, I find that the gif files for my quizzes are no longer showing up. Looking at the questionDB.xml file, I see that the path to graph1.gif, for example is simply src="test_images/graph1.gif".
If I were to edit the questionDB.xml file and replace all src="test_images strings with something else, what should this be? Perhaps http://mywebsite/moodle/...?
Alternatively, if I were to move the test_images directory elsewhere, where would that be? Perhaps somewhere in the moodledata directory?
Is the problem somewhere else.
Thanks in advance for any help!
