Custom thumbnails?[edit]

Help

Hi, is it possible to create a custom thumbnail for an image that will then be served without further reprocessing, and still link to the main image? The standard thumbnail of this <File:Concorde.planview.arp.jpg> as it appears here W:Concorde is being made a right pigs-ear of due to its sharp edges and plain background.

I also ended up with two identical copies of the file in question (same date), as I thought an upload had stalled but it hadn't. Perhaps someone with Admin privs could delete it, save confusion.

Thanks, Trev M 19:32, 14 March 2010 (UTC)

Yes. See w:Wikipedia:Extended image_syntax#Link. For example Loxoceles reclusa iconized thread 48.png should link to the description page of the original image. Another example: Loxoceles reclusa iconized thread 48.png should link directly to a specific uploaded image version. Works in both Commons and Wikipedia. -84user (talk) 16:22, 16 March 2010 (UTC)
Thanks. However, seems like it's necessary to get further under the bonnet (hood). The following posted on the help desk: I prepared a clean, custom thumbnail 300x229 - same size as specified at W:Concorde - and uploaded it to File:300px_Concorde.planview.arp.q8.jpg. The file size is 14 kB, which gives a presentable, fringe-free rendering on my browsers. However, wikimedia is not serving it without further reprocessing - not even to the file viewing window. So I haven't altered the wikipedia thumbnail source yet, as the file source isn't even displayed correctly. I've set my own appearance prefs all over the place and it makes no difference - we get it at 3 929 Bytes, complete with decorative fringes.
Come on guys, you can spare 10k of bandwidth to make this unique thumbnail worth looking at, surely? Where's the disable re-rendering option for specific images?? Trev M 21:00, 16 March 2010 (UTC)

So, my view of wikipedia - images at any rate - are being supplied by a diffrent server. The question is whether that server is a third party server, or something within the control of the wikimedia foundation.

Using http://www.urgentclick.com/ip_address_lookup.php I get:

The ip address for upload.wikimedia.org is: 208.80.152.3

I do a traceroute for 208.80.152.3 I get:

Comment? Trev M 02:29, 18 March 2010 (UTC)

That is strange. Your traceroute for upload.wikimedia.org shows that it goes through 64.214.144.121, which appears to be some server belonging to a network in Phoenix, Arizona. The target upload.esams.wikimedia.org (91.198.174.3), however, is the Wikimedia mirrors in Amsterdam. If you're in the U.S., you shouldn't go to the KNAMS servers in Europe at all; you should be served by the PMTPA servers in Tampa, Florida. Somehow, it looks as if some DNS cache along the way has the wrong settings... You don't have an entry for upload.wikimedia.org in your /etc/hosts file, do you?
That still doesn't explain why you get served a 4kB version of the file. Perhaps there is some intermediary caching proxy along your route? Or the ESAMS server sees that you're coming from far away and decides to downgrade the file? (Don't know if they do that.)
BTW, I get the 14793 bytes version from http://upload.wikimedia.org/wikipedia/commons/d/d1/300px_Concorde.planview.arp.q8.jpg but then my traceroute to the upload server was a surprise:
$ traceroute upload.wikimedia.org
traceroute to upload.esams.wikimedia.org (91.198.174.3), 64 hops max, 52 byte packets
 1  upload.esams.wikimedia.org (91.198.174.3)  1.687 ms  1.393 ms  1.402 ms
$
I would have expected to see at least some intermediary hops. (I'm behind a firewall, and not exactly in the vicinity of Amsterdam either.)
The "access denied" error seems to be a deliberate server configuration; apparently these servers are accessible through http only under the name "upload.wikimedia.org". (I get those errors, too, if I try IP numbers or the esams/pmpta names.)
Anyway, I would suggest that you try to contact one of the system administrators. Maybe they can figure out what might be going on. Easiest way might be through IRC #wikimedia-tech. Lupo 08:13, 18 March 2010 (UTC)
This problems turns out to be my own wireless ISP (Vodafone). It's actually quite a useful feature for getting a faster page loads if one is indifferent to the image quality. If anyone comes here as a result of searching the same issue, there's a couple of workarounds on Macs: for individual pages, Apple-shift-R or Apple-shift+browser_reload_button; for ongoing bypassing of the compression feature, try installing this donate-ware app: http://aitne.com/downloads/ByteMeOptimizer-v1.1.dmg (108kB).

Thanks to all who helped me get a handle on this one!

That still leaves the issue as to why Lupo was getting stuff sent over from Amsterdam. I think we can live with that on.... (I'm in UK in case you haven't twigged yet. I'm just nocturnal! ;-> Trev M 01:20, 22 March 2010 (UTC)

If you're in the UK, I don't understand why your traceroutes show them going through a server in Phoenix, Arizona, U.S. Lupo 07:29, 22 March 2010 (UTC)
after Pheonix, it's GBLX.NET, washington, passing it back to 62.212.95.129 leasenet, amsterdam.
While you're here, as you have admin privs, could you clear up the redundant images at File:Concorde.planview.arp.jpg. The version 18:20, 14 March 2010 is exactly the same as the one before it 18:17, 14 March 2010, so it and the revert from it: 18:23, 14 March 2010 can both go, they illustrate nothing but my struggle with slow uploads and are a potentiall source of confusion to users of the file. To clarify:

There should be 3 versions of the image, and ideally, no more, yet:

  • the clean-up by me User:Trev M 18:17, 14 March 2010 (should be the current version)
  • the clean-up by Arpingstone 13:34, 14 October 2007
  • the original 13:42, 14 May 2005 uploaded by User:Arpingstone

I'll evetually get around to adding the details of the changes I made to the image to the redlinked talk page ref I added.

Finally, what would be the best way to add or refer *to* the thumbnail I made at File:300px_Concorde.planview.arp.q8.jpg from the main file? I don't see any mention of it there.

Thanks for your help, Trev M 13:28, 22 March 2010 (UTC)

Hello, Trev M!

Tip: Add categories to your images

Thanks a lot for contributing to the Wikimedia Commons! Here's a tip to make your uploads more useful: Why not add some categories to describe them? This will help more people to find and use them.

Here's how:

1) If you're using the UploadWizard, you can add categories to each file when you describe it. Just click "more options" for the file and add the categories which make sense:

Uploadwizard-categories.png

2) You can also pick the file from your list of uploads, edit the file description page, and manually add the category code at the end of the page.

[[Category:Category name]]

For example, if you are uploading a diagram showing the orbits of comets, you add the following code:

[[Category:Astronomical diagrams]]
[[Category:Comets]]

This will make the diagram show up in the categories "Astronomical diagrams" and "Comets".

When picking categories, try to choose a specific category ("Astronomical diagrams") over a generic one ("Illustrations"). Pro-tip: The CommonSense tool can help you find the best category for your image.

Thanks again for your uploads! More information about categorization can be found in Commons:Categories, and don't hesitate to leave a note on the help desk.

File:Watchlist whitspace screenshot.png[edit]

Hi there. I've changed licensing to better reflect the screenshot's contents, and changed the file's category from Screenshots to Screenshots of Mozilla Firefox 3.6. Then I modified your upload, so that its contents would be in accordance with Commons:Screenshots#Software. Check image history for a bit more. In all fairness, screenshots of free/open source software in a proprietary OS are tricky, because visuals and elements of proprietary operating systems tend to be rather sticky.
