Batch Download of Photos From Flickr Based on Their Tag

November 20th, 2008 by aizatto

For the FOSS.my event, I wanted everyone to tag their photos with foss.my or foss.my 2008. Because this makes it easier to easily see FOSS.my buzz as it happens on Flickr!

A Tale of Sucky Wordpress Plugins

I was looking for a plugin to grab Flickr photos by a specified tag, so that we can use it in the foss.my gallery. Though there are many Flickr plugins for Wordpress, there was none catered to my requirements. Unable to find a solution, I thought it was quicker to hack one myself.

So this script just expanded from there, and I quickly had a Flickr batch downloader.

Note: There are several requirements:

Download phpFlickr, and unzip it to the same directory as the script.
You need to obtain a Flickr API key.

Use the source

<?
/*
 * phpFlickr 
 *   http://phpflickr.com/
 *
 * Flickr API 
 *   http://www.flickr.com/services/api/
 *
 * Flickr API call flickr.photos.search
 *   http://www.flickr.com/services/api/flickr.photos.search.html
 * 
 * Photos are available via the following format:
 * 	 http://farm{farm-id}.static.flickr.com/{server-id}/{id}_{secret}_[mstb].jpg
 *
 * For more information visit http://www.flickr.com/services/api/misc.urls.html
 *
 * Applying for a Flickr API Key
 *   http://www.flickr.com/services/api/keys/apply/
 */

require_once("phpFlickr.php");

define('VERBOSE', array_search('-v', $argv));

// Download a batch of photos from the given page
function download($photos) {
	$download = 0;
	foreach ($photos['photo'] as $photo) {
		$filename = sprintf("pics/%s-%s.jpg", $photo['owner'], $photo['id']);
		$url      = sprintf("http://farm%d.static.flickr.com/%s/%s_%s_o.jpg", $photo['farm'], $photo['server'], $photo['id'], $photo['secret']);
		if (file_exists($filename)) {
			if (VERBOSE)
				print sprintf("33[33m %-10s %s33[0m \n", "Skip", $url);
			else
				print sprintf("33[33m.33[0m");
			continue;
		}
		if (VERBOSE)
			print sprintf("33[32;1m %-10s %s33[0m \n", "Download", $url);
		else
			print sprintf("33[32m.33[0m");
			
		file_put_contents($filename, file_get_contents($url));
		$download += 1;
	}
	return $download;
}

$flickr  = new phpFlickr("YOUR_API_KEY");
$options = array('tags' => 'fossmy, "fossmy 2008", foss.my, "foss.my 2008"');

$photos = $flickr->photos_search($options);
print sprintf("Available 33[32;1m %d 33[0m \n", $photos['total']);

// Download the first batch of photos
$downloaded = download($photos);

$page  = $photos['page'];
$pages = $photos['pages'];
// Download the following batch of photos
for ($i = 2; $i < $pages; $i++) {
	$options['page'] = $i;
	$photos = $flickr->photos_search($options);
	$downloaded += download($photos);
}
if (! VERBOSE)
	echo "\n";
print sprintf("Downloaded 33[32;1m %d 33[0m/ %d \n", $downloaded, $photos['total']);

Running it

It’s just as a simple as:

php download.php

Sample Results:

Available  492
..................[trim]............
Downloaded  0 / 492

It even comes with a -v flag, so you can view what files are being downloaded.

MyOSS Meetups: Call for Presentations

April 26th, 2007 by aizatto

One problem I’ve had with the Meetups is that during call for presentations, no one submits something. If they do, it doesn’t sound good.

So I’ve set up a page where you can submit a possible presentation topic. Nothing so fancy, but to make it easier for people, not just MyOSS-ers to submit something.

Will anyone lend a hand and give a presentation for the Meetup? I am looking for good (doesn’t have to be) technical talks.

If not, how about any suggestions/improvements to the page?

Ruby Talk at UiTM

April 14th, 2007 by aizatto

I gave a talk about Ruby yesterday (Friday 13th April 2007) at UiTM on Ruby!

Honestly I believe it could have gone better. I think It kind of went too technical, but I don’t know how to steer away from that when talking about language, besides going through a 101. Maybe that would have been best.

Small audience, as many students as lecturers. Less than 20.
