<p><strong>HTML <code>&lt;img&gt;</code> এলিমেন্ট</strong> (বা <em>HTML ইমেজ এলিমেন্ট</em>) ডকুমেন্টের একটি ইমেজকে বোঝায়।</p>
<div class="note">
 <p><strong>ব্যবহার নির্দেশিকাঃ</strong><br />
  ব্রাউজার সবসময় এলিমেন্টের রেফারেন্স করা ছবি প্রদর্শন করে না। এটা নন-গ্রাফিক্যাল ব্রাউজারে (দৃষ্টি প্রতিবন্ধিদের ব্যবহারের গুলো সহ), অথবা যারা ছবি দেখতে চায় না, বা ছবিটির লিঙ্ক ভুল হওয়া বা <a href="#Supported_image_formats" title="HTML/Element/Img#Supported_Image_Formats">অসমর্থিত ধরনের&nbsp; </a>হওয়ার কারনে ব্রাউজার ছবিটি দেখাতে অক্ষম হতে পারে। এসব ক্ষেত্রে ব্রাউজার ছবিটিকে এলিমেন্টের <strong>alt</strong> অ্যাট্রিবিউটের মধ্যে থাকা টেক্সট&nbsp; প্রদর্শন করে।</p>

   <p><strong>Usage note: </strong>Omitting this attribute indicates that the image <em>is</em> a key part of the content, but no textual equivalent is available.

  This enumerated attribute indicates if the fetching of the related image must be done using CORS or not. <a href="/en-US/docs/CORS_Enabled_Image" title="CORS_Enabled_Image">CORS-enabled images</a> can be reused in the {{HTMLElement("canvas")}} element without being <em>tainted</em>. The allowed values are:

    anonymous</dt>
   <dd>
    A cross-origin request (i.e. with <code>Origin:</code> HTTP header) is performed. But no credential is sent (i.e. no cookie, no X.509 certificate and no HTTP Basic authentication is sent). If the server does not give credentials to the origin site (by not setting the <code>Access-Control-Allow-Origin:</code> HTTP header), the image will be <em>tainted</em> and its usage restricted..</dd>

   <dd>
    A cross-origin request (i.e. with <code>Origin:</code> HTTP header) is performed with credential is sent (i.e. a cookie, a certificate and HTTP Basic authentication is performed). If the server does not give credentials to the origin site (through <code>Access-Control-Allow-Credentials:</code> HTTP header), the image will be <em>tainted</em> and its usage restricted.</dd>
  </dl>
  When not present, the resource is fetched without a CORS request (i.e. without sending the <code>Origin:</code> HTTP header), preventing its non-tainted used in {{HTMLElement('canvas')}} elements. If invalid, it is handled as if the enumerated keyword <strong>anonymous</strong> was used.

<h2 id="Supported_image_formats">Supported image formats</h2>
<p>The HTML standard doesn't give a list of image format that must be supported, so each user agent supports a different set of formats. Gecko supports:</p>
<ul>
 <li><a class="external" href="https://en.wikipedia.org/wiki/JPEG" title="https://en.wikipedia.org/wiki/JPEG">JPEG</a></li>
 <li><a class="external" href="https://en.wikipedia.org/wiki/Graphics_Interchange_Format" title="https://en.wikipedia.org/wiki/Graphics_Interchange_Format">GIF</a>, including animated GIFs</li>
 <li><a class="external" href="https://en.wikipedia.org/wiki/Portable_Network_Graphics" title="https://en.wikipedia.org/wiki/Portable_Network_Graphics">PNG</a></li>

</ul>
<div class="note">
 <p><strong>Note:</strong><br />
  Support for the <a class="external" href="https://en.wikipedia.org/wiki/X_BitMap" title="https://en.wikipedia.org/wiki/X_BitMap">XBM</a> format has been removed in Gecko 1.9.2.</p>
</div>
<h2 id="Interaction_with_CSS">Interaction with CSS</h2>
<p>Regarding CSS, an <code>&lt;img&gt;</code> is a <a href="/en-US/docs/CSS/Replaced_element" title="CSS/Replaced_element">replaced element</a>. It has no baseline, meaning that, when used in a inline formatting context with {{cssxref("vertical-align")}}<code>: baseline</code>, the bottom of the image will be posed on the container's baseline.</p>
<p>An <em>image</em> may have an intrinsic dimension, but not necessarily, depending of its type. A SVG image has no intrinsic dimension, a raster image has one.</p>
