The image and design is very important when selling online factor. If the images of their products are cut or deformed or each has a different size, these generate customer confidence and hardly to be sold successfully.
The Drupal image styles to define measures and adjustments are automatically applied on the images we want.
In this trick use product images in different sizes and formats but always with white background.
To get an advanced style set need to install the ImageCache Actions module to complement the core module of Drupal with many more effects; watermarks, canvas, rounded corners, overlay, Aspect Switcher, etc ...)
Once the module enabled page will access management styles (/admin/config/media/image-styles) and add the following effects in this order:
- Scale (with maximum dimensions of the image).
- Define Canvas (# FFFFFF Background with the same dimensions as the previous effect).
