Would it be possible to select what thumbnail size is displayed on the front end (product page) ?
At the moment the 150px x 150px thumbnail is displayed.
I’d like to use a custom size – as defined in my functions.php if possible.
I don’t know of File Manager Settings so I assume you mean:
Yes I can change the thumbnail size there but i was wondering if i could assign a custom image size to be displayed – as defined using the add_image_size(..) in my functions.php
