Hi there,
Thanks, I tried this solution but didn't work.
Problem was because I had SEF (Search ENGINE Froendly) urls 'on', interestingly when I turned it off images did show on all pages.
But i also wanted SEF unred 'ton' for my site. Thanks to your suggestion as it made me think in that direction. Images path should have been relative.
So, I tried putting "../" infront of module on line 79 like:
url(../modules/mod_kwickverti_slidingmenu/kwickverti_slidingmenu/images/<?php echo $camp26image1?>

;
and that worked!!!
thanks for your time and inputs.
and yes your english is not bad at all. You did convey your point well which, helped me solve this issue.
