Thank you. I was trying to reverse engineer the base58 string, and getting close, but no cigar. (If the photo ID space wasn't quite so sparsely populated where I was sampling it, I might have managed, too.)

Richard Cunningham    says:

It would be good if this was translatable to a photo url with out any requests (in the way twitpic, twitgoo, yfrog etc. do).

Just knowing the photo id doesn't get you to photo url since you need the secret, farm and server (http://www.flickr.com/services/api/misc.urls.html). We would have to do a flickr.photos.getInfo for each photo.

unless I'm missing something?

An example for a bookmarklet:

javascript:void(prompt('Flic.kr short ID (base58)',(function(num){if(typeof num!=='number')num=parseInt(num);var enc='',alpha='123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ';var div=num,mod;while(num>=58){div=num/58;mod=num-(58*Math.floor(div));enc=''+alpha.substr(mod,1)+enc;num=Math.floor(div);}return(div)?''+alpha.substr(div,1)+enc:enc;})(prompt('Flickr picture ID'))))

javascript:void((function(){var m=window.location.href.match(/^https?:\/\/[^/]*\bflickr\.com\/(photos\/[^/]+\/(\d+))/i);if(m.length&&m[2])prompt('Short Flic.kr-URL for\n"'+m[1]+'":','http://flic.kr/p/'+(function(num)
{if(typeof num!=='number')num=parseInt(num);var enc='';var alpha='123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ';var div=num;while(num>=58){div=num/58;var mod=(num-(58*Math.floor(div)));enc=''+alpha.substr(mod,1)+enc;num=Math.floor(div);}
return(div)?''+alpha.substr(div,1)+enc:enc;})(m[2]));})())

quick python snippet for encoding...

num=12345678
a='123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ'
bc=len(a)
enc=''
while num>=bc:
    div,mod=divmod(num,bc)
    enc = a[mod]+enc
    num = int(div)
enc = a[num]+enc
print "flic.kr/p/%s" % (enc,)

javascript decoder.

function base58_decode( snipcode )
{
    var alphabet = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ' ;
    var num = snipcode.length ;
    var decoded = 0 ;
    var multi = 1 ;
    for ( var i = (num-1) ; i >= 0 ; i-- )
    {
        decoded = decoded + multi * alphabet.indexOf( snipcode[i] ) ;
        multi = multi * alphabet.length ;
    }
    return decoded;
}

I'm using above base 58 decode function on pbtweet

Great topic kellan!

I've just used your base_encode function on flicktotwitt.com

THANKS!

Tim Parenti    says:

Thanks for the information. I've created a simple, web-based implementation at http://www.timparenti.com/dev/flickr/shortlink/

It's meant for the people who don't necessarily want or need Twitter integration, but just want to convert URLs (although I might add Twitter integration later).

It can handle conversions from a short URL to a photo ID and vice-versa. I'm planning to add full URL support so you can just paste a long URL from your browser bar and it will extract the relevant bit (the photo ID).

If anyone has any ideas to improve it, please let me know. Here's hoping someone at least finds it useful.

Any reason why this can't be incorporated into the "Share This" widget at the top right of each photo page?

kellan    says:

Btw valid paths after the photo id will be passed along now.

So flic.kr/p/$photoid/sizes/l works as do flic.kr/p/$photoid/nearby and flic.kr/p/$photoid/favorites

python decoder snippet
This code based on taiyofj's javascript one,

def b58decode(s):
    alphabet = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ'
    num = len(s)
    decoded = 0 ;
    multi = 1;
    for i in reversed(range(0, num)):
        decoded = decoded + multi * ( alphabet.index( s[i] ) )
        multi = multi * len(alphabet)
    return decoded;

Rex Roof    says:

If these are really Base58, why doesn't the Math:Int2Base perl module work?

Rex Roof    says:

Oooh, because you aren't using regular Base58. you're using Base62 with your own characters removed. Sorry, answered my own question.

robceemoz    says:

my colleague Johnath converted this to a shorter Firefox bookmarklet using the page's contained <link rev="canonical"> tag:

javascript:var%20l=document.querySelectorAll("link");for(i=l.length-1;i>=0;--i){if(/flic\.kr/.test(l.item(i).href))prompt("Have%20a%20url!",l.item(i).href);}

and a simple variation of @robceemoz's post to send it straight to twitter

javascript:var%20l=document.querySelectorAll("link");for(i=l.length-1;i>=0;--i){if(/flic\.kr/.test(l.item(i).href))document.location='http://twitter.com/?status=Just%20posted:%20'+l.item(i).href;}

I've just posted up a Greasemonkey script based on Xenocryst @ Antares Scorpii's bookmarklet (above):

flic.kr Short URL Link
at userscripts.org

It looks like this:



Hope you find it useful!

I revised your initial check against m as such:

Zoolcar9 says:

I wrote a Firefox extension to get flic.kr shortened URL from context menu if you right click on Flickr photo, link, or Flickr photo page. Please try it
