The file is just a file, you need to create an image like so: var _URL = window.URL || window.webkitURL; $(“#file”).change(function (e) { var file, img; if ((file = this.files[0])) { img = new Image(); var objectUrl = _URL.createObjectURL(file); img.onload = function () { alert(this.width + ” ” + this.height); _URL.revokeObjectURL(objectUrl); }; img.src = objectUrl; … Read more
If I correctly understand what you want, you may leave the width and height attributes off the image to maintain aspect ratio and use flexbox to do the centering for you. .fill { display: flex; justify-content: center; align-items: center; overflow: hidden } .fill img { flex-shrink: 0; min-width: 100%; min-height: 100% } <div class=”fill”> <img … Read more
You could use input type image. <input type=”image” src=”http://example.com/path/to/image.png” /> It works as a button and can have the event handlers attached to it. Alternatively, you can use css to style your button with a background image, and set the borders, margins and the like appropriately. <button style=”background: url(myimage.png)” … />

In CSS, you can set an element to display: inline-block to make it replicate the behaviour of images*. Images and objects are also … Read more
Use the below code to save the image to internal directory. private String saveToInternalStorage(Bitmap bitmapImage){ ContextWrapper cw = new ContextWrapper(getApplicationContext()); // path to /data/data/yourapp/app_data/imageDir File directory = cw.getDir(“imageDir”, Context.MODE_PRIVATE); // Create imageDir File mypath=new File(directory,”profile.jpg”); FileOutputStream fos = null; try { fos = new FileOutputStream(mypath); // Use the compress method on the BitMap object to … Read more
Yes, use the File API, then you can process the images with the canvas element. This Mozilla Hacks blog post walks you through most of the process. For reference here’s the assembled source code from the blog post: // from an input element var filesToUpload = input.files; var file = filesToUpload[0]; var img = document.createElement(“img”); … Read more
I think this is a really cool method: /** * Conserve aspect ratio of the original region. Useful when shrinking/enlarging * images to fit into a certain area. * * @param {Number} srcWidth width of source image * @param {Number} srcHeight height of source image * @param {Number} maxWidth maximum available width * @param {Number} … Read more
You can do it by making the background into a pattern: <defs> <pattern id=”img1″ patternUnits=”userSpaceOnUse” width=”100″ height=”100″> <image href=”wall.jpg” x=”0″ y=”0″ width=”100″ height=”100″ /> </pattern> </defs> Adjust the width and height according to your image, then reference it from the path like this: <path d=”M5,50 l0,100 l100,0 l0,-100 l-100,0 M215,100 a50,50 0 1 1 -100,0 … Read more
<a download=”custom-filename.jpg” href=”/path/to/image” title=”ImageName”> <img alt=”ImageName” src=”/path/to/image”> </a> It’s not yet fully supported caniuse, but you can use with modernizr (under Non-core detects) to check the support of the browser.

The resulting diff file displays all pixels which … Read more
