How Does Image Resizing Work for Products?
In your Shift4Shop Online Store Manager, you can set the default sizing for product images that your store will use. This helps in making your image files conform to a specific parameter and give you some uniformity as to how your products are displayed. To set these parameters, go to Settings >General >Store Settings and click on the "Products Display " tab. Within the "Products" section of that page, you will have the following parameters available:
In other words, if you have an image that is 600x600px, and assign it to a product via the Online Store Manager interface, the image will be compressed to the Large Image and Thumbnail Image constraints accordingly. The resizing will occur during the image assigning process. If the original 600x600 image were to be re-uploaded after the product image has been assigned, you will overwrite the sizing.
It is also important to note that images which are uploaded to your site (whether via FTP or the file manager) and then assigned through a CSV import will not be affected by these settings.
Furthermore, please also note that the resizing described here is intended to constrain your images to the entered values. The software will not enlarge images if they are below the size measurements listed in the Online Store Manager
The size confinements will resize and confine your images to be within your specified parameters. Therefore it will resize the largest side of your image so that the overall image falls within the set parameter ranges. In other words, if your main image parameter is set to use the default 300x300 resolution but your image is wider than it is tall - for example; 600px width x 400px height - the parameters will resize the image so that its width falls within the 300 pixel range. (i.e. 300x200)
Alternately, if the image is taller than it is wide (400x600), the parameters will resize it so that its height is confined to the 300 pixel range and make it 200x300.
