Thumnail Generator

[Sheldon]

I loaded the thumnail generator and got the following error messages.

I rechecked and everything is in its right place. (files i mean)

Can anyone help?

I Checked the DIR_FS_CATALOGDIR_WS_IMAGES line and it is written as:

opendir(DIR_FS_CATALOG . DIR_WS_IMAGES).

 

I am posting both the error messages and the code in hopes that it will be helpful.
