Dear thambi yousuf,
I see that there are already 4 images in a row, if you want add 1 image to a row, go to yoursite/modules/mod_sj_k2_categories/assets/css/mod_sj_k2_categories.css and find:
.sj_k2_categories {
margin: 20px 0;
overflow: hidden;
width: 75%;
}
and remove width: 75%;
Then config module Sj Categories for K2 in Module manager. Please edit in Device Class Suffix field:
preset01-4 preset02-3
preset03-2 preset04-2
preset05-1
=>
preset01-5 preset02-3
preset03-2 preset04-2
preset05-1
Thanks
