The Modern Web Guide: Responsive Images (Srcset)
The Adiminium Responsive Image Generator is the ultimate "Do It For Me" tool for modern web development. In the old days, we just had one `img src="pic.jpg"`. Today, that is malpractice. You shouldn't serve a massive 4K desktop hero image to a user on a shaky 3G iPhone connection.
The Solution: `srcset`
HTML5 introduced the `srcset` attribute. It allows you to provide a menu of images to the
browser, and let the browser pick the best one.
"Here is the small one, the medium one, and the big one. You choose."
How This Tool Helps
Creating these assets manually is painful. You have to open Photoshop, resize to 400px, save. Resize to
800px, save. Resize to 1200px, save. Then write the complex HTML code.
This tool does it all instantly.
Standard Breakpoints
We use an industry-standard "Mobile / Tablet / Desktop" strategy:
- 400w: Perfect for mobile phones in portrait mode.
- 800w: Great for tablets or mobile phones with high-density "Retina" screens (2x pixel density).
- 1200w: Standard desktop view.
Workflow
- Upload Master: Always start with the biggest, highest quality image you have (e.g., 2000px wide).
- Auto-Generate: We create the 400, 800, and 1200 versions in memory.
- Copy Code: Grab the pre-written HTML tag. It includes `sizes` attributes for responsive layout hints.
- Download Assets: Download the resized files and put them in your project folder.
