I'm trying to figure out a way to cache the next and previous images in my gallery script ... I'm wondering if this is a good way to do it. Also, is there any way to manually specify the cache time for the downloaded image?

When image has display: none or is inside an element with display:none , the browser may opt not to download the image until the display is set to another value. Only Opera downloads the image when you switch the display to block . All other browsers download it immediately.
Images or wrapper elements that have display: none set, will still get loaded. So if you want to eg. load a different image for desktop and mobile, you can either: use display: none , but with the loading="lazy" parameter set on img .
Image caching essentially means downloading an image to the local storage in the app's cache directory (or any other directory that is accessible to the app) and loading it from local storage next time the image loads.
Yes the browser will cache them, often even when your headers say otherwise.
display: none images will be downloaded and cached on the client. However, JavaScript already has a well-defined way of preloading images:
var nextImage = new Image();
nextImage.src = "your-url/newImage.gif";
This will preload an image without displaying it to the user.
