<p><strong><a href="http://www.hedgerwow.com/360/dhtml/base64-image/demo.php">Cross Browser Base64 Encoded Images Embedded in HTML</a></strong></p> Scarily clever. View the PHP source to see what’s going on—most browsers get image tags that use data URIs starting with data:image/png;base64, but IE gets served a Content-type:message/rfc822 header and a MIME formatted multipart/related document, as used by e-mail clients to embed inline image attachments. <p><small></small>Via <a href="http://blog.hedgerwow.com/2009/04/16/updatecross-browser-base64-encoded-images-embedded-in-html/">HedgerWow</a></small></p> <p>Tags: <a href="https://simonwillison.net/tags/base64">base64</a>, <a href="https://simonwillison.net/tags/browsers">browsers</a>, <a href="https://simonwillison.net/tags/hedger-wang">hedger-wang</a>, <a href="https://simonwillison.net/tags/internet-explorer">internet-explorer</a>, <a href="https://simonwillison.net/tags/mime">mime</a>, <a href="https://simonwillison.net/tags/php">php</a></p>

<p><strong><a href="http://fi.am/entry/urlsafe-base64-encodingdecoding-in-two-lines/">URLsafe base64 encoding/decoding in two lines</a></strong></p> A much better solution than my base65 hack—if you understand how base64 padding works (I didn’t) you can use it to generate URL-safe compressed hashes. Performance should be significantly better than my version. <p>Tags: <a href="https://simonwillison.net/tags/base64">base64</a>, <a href="https://simonwillison.net/tags/base65">base65</a>, <a href="https://simonwillison.net/tags/python">python</a>, <a href="https://simonwillison.net/tags/urlsafe">urlsafe</a></p>
