If you have product whose presentation has to be in a wider image than the default 274×293px, please follow this tutorial:

1 – We recommend that you create a child theme. Please first follow this tutorial.

2 – Put this code into the functions.php in your child theme:

function jaw_child_theme_supports() {
add_image_size('woo-size', 274, YOUR_HEIGHT, true);
}

Change YOUR_HEIGHT to the height you want (e.g. 150)

3 – Now, you have to resize your older images to new size. To be able to do this, please install and activate Simple Image Sizes plugin.

4 – Go to WordPress Setings -> Media and check whether your new size has been set there.

5 – Scrool down and click on Regenerate Thumbnails.

6 – Now, your thumbnails should have a new size.

Older versions of GoodStore was used 170x187px photo for “small” size of product box. But on mobile devices it was ugly. So we considered to use a little bit larger photo 275x???px. This new size looks OK on mobile devices.
