Hi
You need to access the file ja-vars.php
1. Check line 66 is recording you header image names:
$ja_header_images = array(‘sh01′,’sh02′,’sh03′,’sh04′,’sh05′,’sh06’);
You header directory will need to have all of your files available or else the header will default to the next file.
This should be changed to ‘head01’. ‘head02’ etc to reflect your file names
2. Check that line 70 is set to 1:
$ja_header_type = 1
It could be that this is set to 2 which sets random headers.
The settings are
0: no header image; 1: header image for each menu item; 2: random header
Good luck
