MediaRSS feed (for PicLens, and others ?)

[AndrewRH]

Hi,

I am wondering if Coppermine supports (or will support) something called "MediaRSS".  Or, perhaps there is a plug-in that does?

I didn't find any reference to MediaRSS when searching these boards; but I did find a reference to RSS that may be similar (RSS feed of pics for Google Screensaver ).

Before I go ahead with the plug-in mentioned there, I wanted to be sure its what is needed...so anyone's help would be appreciated.

A brief background...
There is a plugin for Firefox called "PicsLens" which will let you see the images full-screen by hovering over their thumbnail.

A sample photo site with MediaRSS that works with PicLens is here: http://www.emilysphotosite.com/

The Wikipedia says MediaRSS was started by Yahoo and describes it as:

Media RSS allows for a much more detailed description of the content to be delivered to the subscriber than is covered by the RSS standard.

Thanks for a great photo system (my site has four years worth of photos and videos of my kids!  Great for the grandparents!),

If you install the RSS / Atom feed mod your gallery will work with PicLens. I removed EasyRSS and installed this and it works fine.

Wow, it works!!! The only problems is that only works for the images that I see in the bottom of the gallery, in my case the latest uploaded, but not if I enter in an album. How can I make it works also inside an album?

[shiftsrl]

Sorry, dumb question. The plugin works only that way...

[shiftsrl]

Well, due to the fact that this plugin works, it's not possible for a willing coder out there to take the code and make it work also with albums and categories? I ask this since I've seen in the readme file

Limitations
------------------------
This plugin can't identify albums or categories name. It's only display the latest 10 photos (tweakable) in the RSS feed.

and this is a shame since this plugin works perfectly with piclens...

[mrbones]

Well, you can "tweak" it a little ... just open the xfeed.php file and edit the following line:

//*** user tunable ***
$upperlimit = 10; //feed limit

I use:

//*** user tunable ***
$upperlimit = 2000; //feed limit

and it displays the last 2000 images that have been uploaded. I believe that this is more than enough. Furthermore, I have tested it with 10000 as well -- no problems. Stil, I miss the option to displays the images by categories ... but the world is not perfect after all .

[ryback]

Hi,

it works great. But there is one security hole. If there are private photos or private album in last ten (or XX) photos, they are shown as well as non secured pictures :-(

Thank you for the excellent RSS feeder Colin, works brilliantly with google photo's screensaver and Piclens.

I'm trying to get piclens working in a safe/local environment, (while I try and get my gellery and piclens working on the playstation 3), and so far I've got place holders for the thumbnails, but no images.
I'm wondering if the mediaRSS feed is dependant on any specific modules?

[PeterLawrence]

Here is an updated version of the xfeed.php file which will output results for a given album if specified.

Now for example entering  xfeed.php?album=10 will display a Media RSS feed for just album 10.
However, if you don't specify an album it works as before.
Note this php still has the same security hole as the original xfeed.php regarding private albums/photos.

[PeterLawrence]

Here is a revised version which should only display images for which the user is allowed to view.
I've added a call to get_private_album_set() and then check to see if the required album is not in the FORBIDDEN_SET_DATA list.
