How to Upload, Preview & Download Image using JavaScript & PHP

Hello reader, Today in this blog, you’ll learn how to Upload, Preview & Download Image using JavaScript & PHP. Earlier, I’ve shared many blogs related to PHP [ Custom Simple PHP Chatbot, Send Email from Localhost, Login & Signup Form with Email Verification], and many more. Now time to create another program (Easily Download Image through URL) using PHP.

In this program [Image Download using PHP], on the webpage, there is an image preview box with an image gallery icon, one input field to paste the image URL, and a button to download the image. This input field is fully validation that means the user can’t upload any other URL except images. When you paste a valid image URL which has like .png or .jpeg extension then there is shown a preview of that image, and the download button also active to download the image, by default the download button is disabled at first. When you click on the download button, it immediately downloads the image.

If you’re feeling difficult to understand what I am saying. You can watch a full video tutorial on this program [Download Image using JavaScript & PHP].
