When using hotpotatoes files, a new html files are generated |

|

in the hotpotatoes folder to display the test. |
|
1038
|
|
|
The genuine html file is copied to math4.htm(user_id).t.html |
|
1039
|
|
|
Images files are not copied, and keep same name. |
|
1040
|
|
|
To check the html file visibility, we don't have to check file math4.htm(user_id).t.html but file math4.htm |
|
1041
|
|
|
In this case, we have to remove (user_id).t.html to check the visibility of the file |
|
1042

For images, we just check the path of the image file. |
