WooCommerce
Q : Images looks not sized correctly, what can I do?
A : Please go to “Appearance > Themes” then activate another theme like “Twenty Fourteen” and then activate “Contrast” again.
Or, go to “WooCommerce > Settings > Catalog : Image Options” then change sizes manually like below;
Catalog Images : 300×300 (uncheck Hard Crop)
Single Product Image : 600×600 (uncheck Hard Crop)
Product Thumbnails : 150×150 (uncheck Hard Crop)
If you feel you have to re-generate all thumbnails, we strongly recommended “Regenerate Thumbnails” plugin by “Viper007Bond“.
