A few platforms allow you to create a folder, drag and drop images into it, and then embed that folder into your HTML so that it displays every image.
Using Imgur, a free image hosting service, is one choice. You can register for an account on Imgur and then make a new album. After that, you may drag and drop pictures into the album. You can copy and paste the embed code into your HTML document after the images have been uploaded.
Flickr is an additional free image hosting service that you can use. You can register for an account on Flickr and then make a new album. After that, you may drag and drop pictures into the album. You can copy and paste the embed code into your HTML document after the images have been uploaded.
An album can also be embedded using Google Photos. Make an album and then select the "Share" option to accomplish this. Copy and paste the link into your HTML document after choosing the "Get Link" option.
Lastly, a code snippet can be used to embed an album. More technical knowledge is needed for this option than for the other options mentioned above. To begin with, make a folder on your server and add the images to it. Next, locate the images' URLs and the folder's URL. Create a snippet of code now that references the image and folder URLs. The code snippet can then be copied and pasted into your HTML document.
I hope this is useful.
