Auto Reload ♻ Image 🖼 on Web Page
The basic process of auto refreshing an image on a web page simply involves adding a search query to the end of an images src. An images src is the web address of the image on the web server. By adding a different search query at the end of the images location on the web server, it forces the web server to serve up a fresh version of the image instead of pulling the image from cache. This is because the web server is tricked into believing it is a different image being requested.
The easiest and most logical way to ensure a unique search query, every time we wish to auto refresh the image is to use the current time, including seconds, for the search query.

Here is a list of this you want to change in the image you wish to auto refresh's HTML code below:
- The id of the image. The example below is
idOfImageToReload but obviously you want to change that to whatever the id is for your image. Also be sure to change the id in the javascript function built into the images HTML code - document.getElementById('idOfImageToReload'). - The alt tag. The example below reads
Image of whatever your image is. Change it to whatever you want your auto refresh image's alt tag to be. - The height and the width of the image.
- How often you want the image to auto refresh. The number in the code below is
5000 which means 5 seconds. How ever number of seconds you want the image to auto refresh change that number and multiply by 1000. If you want the image to auto refresh every 30 seconds you would change that number to 30000 (note: no commas in the number).

In Javascript, this is accomplished via the setInterval function.
Here is the basic Javascript code to auto refresh an image at set intervals:
1:
2:
3:
4:
5:
6:
7:
var varImgToAutoRefresh=document.getElementById("idOfImageToReload");
var varImgSrc=varImgToAutoRefresh.src;
setInterval(funcRefreshImage,5000);
function funcRefreshImage(){
varImgToAutoRefresh.src=varImgSrc+"?time="+new Date().getTime();
}
