Image Guides
Practical, original explanations for image compression, formats, dimensions, ecommerce assets, accessibility and web delivery.
ImageRW guides are designed to answer the questions that come up when a file has to work somewhere specific: a website, an online store, an email, a document or a responsive page. Each guide explains the trade-offs instead of treating one setting as correct for every image.
