This is exactly what i had meant. I never realized that u wouldn't know how to insert the html code for a picture. i thought you are inserting the code correctly but the folder in which it is located is not publicly accessible etc.
Actually this is the best way of doing this also because you can then do the following:
- lets say you have a folder called www.yoursite.com/images
- put ALL your images there in various folders. eg. test1, physics1, chemistry1 etc
- Create your tests offline in textpad/notepad. A question would look like this:
- which is the correct diagram for water's behaviour with change in temp?<img src="http://www.yoursite.com/images/physics1/q1.jpg"> { ~A ~B ~C ~D =E}
Security: since images is a public folder, the students(who are pretty smart) may right click on images during quiz and locate the url of pictures. so do the following:
1. server: set server settings not to allow raw listing of directory contents
2. always show quiz in secure window where right click is disabled
3. enable hot-link protection on your site
This will provide some security, though nothing is fool proof.
