Image resize problem

[eluser]Bigil Michael[/eluser]
thanks for your help.
used your code. but the result is same.

when i remove the code for thumb

Code:

$config1['maintain_ratio'] = FALSE;
$config1['width'] = 100;
$config1['height'] = 100;
$config1['create_thumb'] = TRUE;
$config1['thumb_marker'] = 'thumb_';

all images will resize. So i think problem is in thumb generation.
