Ok, sorry – took me some time to get to it. :)

This format of link

interfacelift.com/wallpaper_beta/dl/imageidentifier_widthxheight.jpg

seems to work differently depending on referrer. So clicking on such link from piped feed doesn’t work BUT pasting such link in address bar does.

Luckily it seems to work in JBS as well so I changed link format in my pipe and now testing it. Works fine so far.

Ok, now about your delicious feed.

First – wth you actually need MediaRSS for? :) Delicious puts link to image in enclosure tag which JBS is supposed to understand. I added your feed (without using pipe) to JBS and it shows non-interfacelift images just fine.

So why exactly you went looking for MediaRSS if it works without it? :)

For interfacelift images try bookmarking that link format /wallpaper_beta/dl/ before it gets signed.

So I took your Pipe and cloned it, the result of which can be found here: http://pipes.yahoo.com/danrough/interfacelift2mediarss

It would appear though that they are using the session variable or something to sign requests because I now get an error when I click on a link in the feed to the download location.

I’m not sure how to proceed on this.

I’ve just done a little more investigation on this and have noticed that they as you suggest, must be signing requests to their image server. Looking at the site proper, when you have selected an image size the Download button then builds a link of the following format:

interfacelift.com/wallpaper_beta/dl/imageidentifier_widthxheight.jpg

Meaning that to request the bamboo picture that was recently posted you would need to construct your link as follows:

interfacelift.com/wallpaper_beta/dl/01905_bamboo_1920x1200.jpg

I’ve tested whether or not the signed request relies on a session cookie by opening a browser from fresh that hasn’t ever been to interfacelift and pasting the above url in which works as it then bounces me to an address that contains the signed portion. Whether this could be relied upon within JBS, I’m not sure, I need to alter my Yahoo Pipes implementation. Given that mine contains some links to content that isn’t on interfacelift, for now I might clone yours and see how it goes.

I’ll keep you informed.

If you know how to do conditional replacements within Pipes (and I’m guessing that this is where the String RegEx module comes in) only on interfacelift content some advice / guidance would be really appreciated.

Cheers, Dan.

Thanks, that had me stumped last night too. I did a little more investigation but even going to http://interfacelift.com/wallpaper_beta/Download/imagename_widthxheight.jpg doesn’t seem to do the trick either so I must confess that at that point, I gave up with the intention of looking at it again today.

Let me know how you get on and I’ll do likewise for you.

Cheers, Dan.

I took quick look, seems my pipe is broken as well because format of links to images had changed.

Even worse it now seems that links became dynamic. So if you save direct link to image in delicious it will expire and stop working after some time.

For example you have tagged
http://interfacelift.com/wallpaper_beta/D9e668a7/01903_summervines_1920x1200.jpg

but it now returns 404 and working link from site is
http://interfacelift.com/wallpaper_beta/D8091f8c/01903_summervines_1920x1200.jpg

I will look into changes and try to update my pipe (if possible at all with new format), stay tuned. :)

I just came across this post whilst browsing for an answer to an issue I have been seeing with John’s Background Switcher. Your solution was the same as mine, to use Pipes that is except you managed to get yours to work [1]! So thanks for publishing this, it’s been really helpful.

So that others that come here, I’ve also published the work that I did to alter your implementation to suit my needs [2] here: http://pipes.yahoo.com/danrough/deliciouswallpapertagtomediarss

[1] I continue to get an error saying John’s Background Switcher [feeds] – Not found. Did you get this at any stage, if so what was the issue?

[2] My requirements were subtly different to yours in that I use delicious and then tag all the wallpapers that I want to display using wallpaper and get the rss feed from there and enter it into JBS as an rss feed (I was suffering the same issue as you in that it did not meet the MediaRSS specification)
