If you don’t care about the image contents, PIL is probably an overkill. I suggest parsing the output of the python magic module: >>> t = magic.from_file(‘teste.png’) >>> t ‘PNG image data, 782 x 602, 8-bit/color RGBA, non-interlaced’ >>> re.search(‘(\d+) x (\d+)’, t).groups() (‘782’, ‘602’) This is a wrapper around libmagic which read as few … Read more
First of all, you should make an HTML form containing a file input element. You also need to set the form’s enctype attribute to multipart/form-data: <form method=”post” enctype=”multipart/form-data” action=”/upload”> <input type=”file” name=”file”> <input type=”submit” value=”Submit”> </form> Assuming the form is defined in index.html stored in a directory named public relative to where your script is … Read more
You need to use cat to get the contents of the file named ‘DSC_0251.JPG’, rather than the filename itself. test=”$(cat DSC_0251.JPG | base64)” However, base64 can read from the file itself: test=$( base64 DSC_0251.JPG )
HTML5 says <input type=”file” accept=”image/*”>. Of course, never trust client-side validation: Always check again on the server-side…
I think this is very nice and short <img src=”https://stackoverflow.com/questions/3984287/imagenotfound.gif” alt=”Image not found” onerror=”this.src=”imagefound.gif”;” /> But, be careful. The user’s browser will be stuck in an endless loop if the onerror image itself generates an error. EDIT To avoid endless loop, remove the onerror from it at once. <img src=”https://stackoverflow.com/questions/3984287/imagenotfound.gif” alt=”Image not found” onerror=”this.onerror=null;this.src=”imagefound.gif”;” /> … Read more

You can use title attribute. <img src=”https://stackoverflow.com/questions/12105214/smiley.gif” title=”Smiley face”/> You can change the source of image as you want. And as @Gray commented: You can also use the title on other things like <a … anchors, <p>, <div>, <input>, etc. See: this
Here’s a gist which does this: https://gist.github.com/dcollien/312bce1270a5f511bf4a (an es6 version, and a .js version which can be included in a script tag) You can use it as follows: <input type=”file” id=”select”> <img id=”preview”> <script> document.getElementById(‘select’).onchange = function(evt) { ImageTools.resize(this.files[0], { width: 320, // maximum width height: 240 // maximum height }, function(blob, didItResize) { // … Read more
