This plugin enables upscaling of thumbnails for small media attachments. The default behaviour of WordPress is to not upscale small images, which means 
you are never guaranteed a certain size for a thumbnail format. This plugin corrects that and upscales small images to the specified thumbnail dimensions. 
This is beneficial in grid layouts where images of different sizes can make the grid malfunction.
