My theme automatically creates thumbnail versions of the featured image. YARRP automatically uses the full featured image, and squashes it down to fit.
The only difference is "-150x150" on the end of the filename.
test.jpg is the featured image.
test-150x150.jpg is the automatically created thumbnail.
Is there a place in the code i can simply add in "-150x150" so that YARRP uses the thumbnails that have already been created? :)
