The Flickr Thumbnails Photostream plugin makes including and linking to photos on a Flickr account simple and flexible.
Extract the "flickr-thumbnails-photostream" folder from the downloaded file and put it in your WordPress "/wp-content/plugins/" folder so that the resulting path is "/wp-content/plugins/flickr-thumbnails-photostream/".
The plugin should now be viewable in the WordPress admin panel under the "Plugins -> Plugins" menu option. The plugin is entitled "Flickr Thumbnail Photostream" and can be activated in the normal way by clicking "Activate" in the far right column.
First, click on the "Flickr Control" option found within the main "Plugin" menu, and you will be directed to the Flickr Control panel. From here you should be able to select how many photos you want to display and other options.
The two most important attributes to get working are your Flickr API Key and your Flickr user ID. Without these two codes it is impossible to connect to your Flickr account.
The Flickr API Key has to be applied for, if you don't currently have one. If you using this plugin for non-commercial use then you should apply for a non-commercial Key. If you do this you should get your Key almost instantly. If you apply for the commercial Key it may take some time to process. You can apply for an API Key here:- http://www.flickr.com/services/api/keys/apply/
If you know or think you already have an API Key then you can retrieve it from here:- http://www.flickr.com/services/api/keys/
Your user ID or NSID is quite easy to find its located in the address/url bar of your web browser when you are on the "Your Photos" page in your Flickr account. It appears just after http://www.flickr.com/photos/
For an example this is how PlusNet's NSID is displayed:- http://www.flickr.com/photos/23469361@N07/
So the NSID here is 23469361@N07
Next you can fill in the amount of photos you want to display.
Simply put, this option will set the number of photos that are to be randomly selected from your cached data, that you will then see on your web page.
Please note: the Flickr API imposes a maximum of 500 photos that can be retrieved from your photo collection at any one time. If you have over 500 photos in your Flickr account, then any number that you enter here, for example 300, will be taken from the latest 500 photos. Only photos set as "public" in your Flickr account will be retrieved.
Once you have filled in these options you need to click the "Update Options" button to save your preferences. Obviously you will need to update the options each time you change them.
To populate the cached data stored in the WordPress database with your photo information you will need to click on the "Update Photos" button. It may take a few minutes to run depending on how many photos you have on your Flickr account. This potentially extended download time is the reason why we have separated this function from the main display function.
The plugin enables you to randomise the photos that are displayed. This function in switched on by default but you can turn it off if you wish. If this function is disabled the plugin will use the latest images on your Flickr account.
Depending on how you use and implement WordPress/your website, you may have to use the widget control menu to position where the Flickr application will appear and be utilised. To do this simply visit the "Presentation -> Widgets" menu option, and position the plugin where ever you like. In some cases it will be necessary to perform this task for the plugin to appear on your web page.
