Quickly disable drag and select for images with CSS. The property user-select: none; blocks selection, while -webkit-user-drag: none; prevents dragging in WebKit browsers. Include draggable="false" for other browsers for an ironclad solution:

<style>
  img {
    -webkit-user-drag: none; /* Bye bye, drag */
    user-select: none; /* You shall not select! */
  }
</style>

<img src="image.jpg" draggable="false"> <!-- Stick like a postage stamp -->

This code snippet ensures your image remains as unmovable as a stubborn mule.

Wide-ranging browser compatibility

The main solution works swimmingly in modern browsers, but to cast the net broader for full cross-browser compatibility, consider these enhancements:

img {
  -webkit-user-drag: none; /* Chrome and Safari can't budge this */
  user-select: none; /* Universal no-touch rule */
  -moz-user-select: none; /* Special rule for Firefox */
  -ms-user-select: none; /* IE and Edge also get boundries */
  pointer-events: none; /* Mouse events? Nope. */
  unselectable="on"; /* A friendly reminder for old IE and Opera */
}

By including browser-specific prefixes like -webkit-, -moz-, and -ms- you're essentially placing a no drag and select sign that's visible across all browsers. Plus, pointer-events: none; goes a step further by disabling mouse events altogether. The HTML attribute unselectable="on" throws a bone to old versions of Internet Explorer and Opera, where CSS alone might not suffice.

Display alternatives for non-interactive images

For scenes where you'd rather display images that are as interaction-proof as a painting behind a glass frame, consider a div with a background-image instead of an img element:

<style>
  .non-interactive-image {
    background-image: url('image.jpg');
    height: 200px;
    width: 200px;
  }
</style>

<div class="non-interactive-image">
</div> <!-- Here lies an image, undisturbed and non-interactive as a ninja in stealth mode -->

This method elegantly sidesteps the need to call in additional attributes or properties since background images are about as interactive as watching paint dry.

Digging deeper into CSS properties

To craft solutions as fine-tuned as a precision watch, it's crucial to grasp the nuances of CSS. Here's an X-ray view of the key properties:

user-select: none;: This property is to preventing text selection what repellent is to warding off mosquitoes.
-webkit-user-drag: none;, -moz-user-select: none;, etc.: These vendor prefixes have your back in older versions of WebKit (Safari, old Chrome) and Mozilla browsers.
pointer-events: none;: This property makes the element as non-interactive as a ghost to mouse events.

Apply these properties as parsimoniously and purposefully as a gourmet chef uses truffle oil. Remember: A heavy hand can hamper accessibility and user experience.

Trouble alert: Common pitfalls to steer clear of

Like a sneaky shapeshifter, CSS has a knack for throwing curveballs. Here are a few common chin-scratchers:

Inconsistent Behavior: Despite your best efforts, some outdated browsers might stick their tongue out at your CSS rules, so testing across browsers is as essential as bringing an umbrella in a rainstorm.
Dragging via Touch Events: Mobile browsers can sidestep your defenses with touch events, which may not be blocked by pointer-events: none;. Always keep an eye on your user base and their potential mobile interactions.
Overzealous use of pointer-events: While pointer-events: none; can work like a charm, casting it far and wide on interactive elements will disable all mouse-based interaction. That's like throwing out the baby with the bathwater!
