Q: Should you lazy load images?

Since most lazy loading solutions work by loading images only if the user has scrolled to the location where images would be visible inside the viewport, those images will never be loaded if users never get to that point.

Q: Should I use lazy loading?

There is a reason for lazy loading. If you know you wont use your specific data a lot it is just about right to load it lazy. You should avoid it if your not completely familiar with lazy loading as you might cause errors.

Q: How do I know if lazy load is working?

If you want to test the execution of lazy loading, I can recommend that you clear your browser's cache and try reloading. Also by using a free tool called FiddlerTool, you can simulate modem speeds through the menu item: Rules → Performance Settings -> Simulate Modem Speeds.

Great until I realized I couldn't use one form to save in different ways. I had to go back and delete and rewrite for each person I was filling the form out for.

Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.

How do I load an image into a scroll?

Find window size and find the position of all images and their sizes. If the image is not within the window size, replace it with a placeholder of same size. When user scrolls down, and position of image < scroll + window height, the image is loaded.

Should you lazy load images?

Since most lazy loading solutions work by loading images only if the user has scrolled to the location where images would be visible inside the viewport, those images will never be loaded if users never get to that point.

Why images are lazy load?

Lazy loading images means loading images on websites asynchronously that is, after the above-the-fold content is fully loaded, or even conditionally, only when they appear in the browser's viewport. This means that if users don't scroll all the way down, images placed at the bottom of the page won't even be loaded.

How can I get lazy loading?

The basic idea of lazy loading is simple — defer loading anything that is not needed right now. For images, it usually translates to any image that is not visible to the user up front can be lazy loaded. As the user scrolls down the page, the image placeholders start coming into viewport (visible part of the webpage).

How do you load asynchronous images?

The way to asynchronous load (lazy load) the content is to not set the 'src' attribute and then execute a script that loads the images once DOM-ready is launched. Var IMG = new Image(), URL = “dying. Jpg”, container = document. getElementById(“holder-div”); IMG.
