First up is a flickr trick I learned so long ago that I remember easily the URL needed to make it work. It’s… magic.
Snap That Magic flickr photo by cogdogblog shared into the public domain using Creative Commons Public Domain Dedication (CC0)
I am a huge fan of flickr, I joined in 2004 a month after they launched. Creative Commons was baked n almost from the start. It’s my place for not just posting my photos (all CCo, that’s another story), but finding open licensed ones to use for my work, but also participating in groups and discussions.
That photo above is found at the web address https://www.flickr.com/photos/cogdog/32604140575/ where you find key information, like the creator (me), a caption, date, tags, license etc.
It’s not obvious to most, but the image file names for a downloaded flickr image have an important pattern, like for the above image, I get this file name for the large size-
What I find is that often you come across file names like these uploaded to a web page, or in a file sent by email. And there is no obviou way from just a flick file name, to get to the info that is included on the flickr URL where the image came from.
The Burger Pic
Here is an example, for a Connect post elsewhere I did an Creative Commons filtered google image search for the word “hamburger” and landed on an article from the Hillsdale Collegian, a Michigan college newspaper (the oldest according to the footer, I read web page footers!)
The picture is perfect! But alas, the author has fallen way short of proper TASL attribution, there is title, author, source or license, just the text “Flickr”. No link at all.
Sure I could have done a reverse image search (which you will see why below would have failed). But I have a direct trick because I can see from the file name of the image in it’s URL that it looks very much like the flickr file name:
So I am fairly confident that this is the image file downloaded from flickr. Let’s apply some magic
The Flickr URL from File Name Trick
So here is the trick for tracking down that burger from its file name
Flickr file names always have a structure where parts are separated by an underscore:
- First is the flickr photo ID and this is the one we need or 4958831
- Next is a “secret” ID used for the flickr API, we can ignore it a1845ea075
- The last letter is a code for the size, o is the code for the original size of the uploaded image
Again, the most important thing is the first series of numbers in the file name, up to the first underscore. We append that string of numbers to the Magic Generating URL:
BOOM! We can get from the file name alone the URL for the source flickr page or https://www.flickr.com/photos/taedc/48574958831/ I now know:
- The burger photo was posted to flickr by Ted Eytan
- It was taken on August 18, 2019
- The photo was licensed CC BY-SA (note that that condition was not satisfied)
- Ted’s camera was a Sony ILCE-6500
- and on, flickr provides so much juicy metadata.
I feel like a web MacGyver every time I do this.
This is All Nice But What About a Practical Use?
I incorporate this into my work flow- if I download an image to use in flickr, say one for a project where I need a photo to represent a magic item, I might get a file named
rather than naming it something like
magic_item.jpg so I know what the image is for, I just prefix the file name when saved on my computer, to be like:
Why? If I did not keep track of the source of the image, my flickr magic trick can get me to it.
Now it is your turn, see if you can find the flickr web page for this photo, and look for a message there.
Mmmmm image magic.
