Sravan92

and i found these.. there are around 5 sizes ..

/*
* Featured images settings
*/
set_post_thumbnail_size(72, 60, true); // used in many more aspect ratios

add_image_size(‘motive-grid-slider’, 603, 362, true); // main slider image in grid slider – also used for main higlights
add_image_size(‘motive-image-block’, 333, 200, true); // gallery sizes used in sidebars and so on – also used in slider at 301×181

add_image_size(‘motive-alt-slider’, 740, 357, true); // alt slider image size
add_image_size(‘motive-slider-full’, 1206, 410, true); // alt slider full-width image size
add_image_size(‘motive-slider-alt-block’, 352, 169, true); // alt slider right slide blocks image

add_image_size(‘motive-main-block’, 252, 167, true); // main home block – used in 232×154 too
add_image_size(‘motive-highlight-block’, 359, 201, true); // also used in highlights blocks at 348×195

so can i delete remaining pics except these ?

Hi Steve, Thank for the reply. I have posted my functions.php code in the above reply.

So, Can you please guide me how to solve this thing ?

What are the duplicate image sizes that i can delete ?
