If I switch over the size of images I want to show for k2 items (uploaded in image tab while adding or editing an item), it doesn't reflect on front end at all. all I mean is like if I have image size parameter set as 100 px for xsmall image when I uploaded picture to an item, but if I change it now, it doesn;t change on front end. If i delete the image from media/k2/items/cache folder, it remove images from all over even from the item edit page. can anyone help me out how I can get resized image on front end withouot re uploading all pictures again to my 100s of items.?
