Using Base64 encoded images on IE too
Filed under : General
Being able to use data: URIs to do interesting things such as inline images is incredibly useful.
IE 8 added support for data URIs but what about older versions of IE (which are still far too prevalent)?
This nice PHP script shows how you can send back data URIs for those who support it, and for older IE, use the message/rfc822 mime type that email clients often use to encode images:
PHP:
-
-
-
MIME-Version: 1.0
-
Content-Type: multipart/related; boundary=“NEXT_MHTML_DATA_PART”
-
-
–NEXT_MHTML_DATA_PART
-
Content-Location:
-
Content-Transfer-Encoding: quoted-printable
-
Content-Type: text/html; charset=“utf-8”
-
-
<!– put the HTML in here including a for loop displaying: –>
-
<div class=“img” style=“background-image:url(MHTML_IMG<?php echo $index?>)”></div>
-
-
–NEXT_MHTML_DATA_PART
-
Content-Transfer-Encoding: base64
-
Content-Type: image/png
-
-
<!– the image data here –>
-
-
–NEXT_MHTML_DATA_PART
-
Content-Location: END_OF_MHTML_FILE
-
Content-Transfer-Encoding: base64
-
Content-Type: image/png
-
IE_NEED_THIS_TO_END_DATA

Very nice, via (@simonw) 🙂
