Hi Florian,

Short question here.

To reduce the lazySizesConfig.expand should we use this code snippet with a single number like the one you provided in the plugin settings?
```
window.lazySizesConfig = window.lazySizesConfig || {};
lazySizesConfig.expand = 300;
```
Or an interval of two numbers is needed instead of a single number, like the one mentioned on GitHub:

lazySizesConfig.expand (default: 370-500)

Thank you,
Andrei

Hi Andrei,

good question, I would say a single number. When I understand the text on GitHub correct, the script picks a number between 370 and 500, depending on the screen size.

After looking into the code, the script seems to use 370 as a value for screens that are smaller than 500×500 and 500 for larger screens (https://github.com/aFarkas/lazysizes/blob/b7827a61200ef06e85287f6f178b1806f15916b9/lazysizes.js#L368). So I think: single value 🙂

He also uses single values in the demos for the data-expand attribute: https://github.com/aFarkas/lazysizes/tree/b7827a61200ef06e85287f6f178b1806f15916b9#data-expand-attribute

Best,
Florian

Hi Florian,

I have been doing some testing loading a page with an image positioned far away with scrolling at the bottom.

Using a value of 100 or 200 will not load the image on page load.
Using an interval of 100-200 will load the image on page load, so somehow I believe using an interval will not work correctly.

Not sure if this is the correct way of testing this. But is consistent with your recommendation of using a single value.

Thank you,
Andrei

sounds like a valid test case for me 🙂
