Cut off my picture of product

Short answer:
You may need to hire a developer to assist you with this issue.

Longer answer:
If you are looking to solve the problem yourself, you will need to identify where (within the code) the image size (215×317) is being declared. This code could be in either the plugin responsible for the store – or in your theme.

If you are looking to show the entire image, you will also need to consider the wider implications this may have on the layout.
Questions you will need to consider;
– Are all your source/original images the same size?
– This style of layout assumes all pictures will be the same height and width. If you decide you want wider images, are you happy to reduce the amount of “columns of products” to 2?
– Alternatively, are you happy for the height (i.e. overall size) of the images to be reduced – such that the entire width may be shown in a 3 column layout?

Your store has a list view already (note the “View as” text at the top of the product grid).

You should check your plugin’s settings, to see if this can be enabled as some kind of “default display option”.

The above would be considered “the right way to do this”.

Alternatively, if you run the following javascript from your theme’s footer.php this may be sufficient:

<script>
jQuery( document ).ready(function() {
    jQuery( "ul.products" ).addClass("list").removeClass("grid");
});
</script>

This only solves part of the problem for you though – as it doesn’t affect the size of the images. If it’s any consolation – I don’t think the page looks bad in it’s current grid state.

Be very careful changing files on your site. I am assuming you are changing these files in a test environment, or via FTP. Please note, if you use WordPress’s built in editor – there is a real risk that you can break the site and will need to login via FTP to remove the change you introduced.
