ImageResizeBot

This is a proposal for an automatic process run by Eagle 101 to resize oversized non-free images according to WP:NFC#3b

The concept is very simple. We have ~8,000 - 9,000+ oversized non-free images. By this I mean the images are obviously too large, and we can make these images smaller by resizing them down to the size of the thumbnail on the image page. For example, lets consider Image:Logchart.jpg. Its 7,808 × 4,448 pixels, very large for an unfree image. As such, this should be resized to a smaller number. I've arbitrarally chosen the size of the thumbnail itself to be the new size, that would be 800 × 456 pixels. Quite a difference in size eh :).

The bot will do all the work of resizing the image to the correct size (a ratio from the thumbnail size), and uploading this new revised image to the encyclopedia. The only tag that I can forsee the bot needing to apply is directly to the image page itself, so that an administrator can come along and delete the old oversized revisions. Thistag is {{furd}}, fair use reduced. If we desire, we can have the bot notify the uploaders, but in this case I feel this is overkill as there will be no noticable differences to the image inthe article.

The bot will resize all images larger then 360,000 square pixels, this can be changed and adjusted if need be. 360,000 pixels is equivalent to a 600x600 square image.

Again, the bot should have no effect on how existing images render in the articles themselves, just the full sized image will be reduced. As such I ask that this bot be allowed to operate at about 3 uploads per minute until the backlog is cleared. This will require about 40-50 hours of operation.

I do request that as soon as we agree this task is desired, even if we don't agree to all the parameters, that I be allowed to test the bot on a few fake images. :) In addition, I'll have the perl source released as soon as I finish basic testing (making sure we can upload etc). —— Eagle101Need help? 18:57, 17 March 2008 (UTC)[reply]

Discussion

  • Sounds like a great idea. What program / software will be used to do the reductions? --MZMcBride (talk) 19:23, 17 March 2008 (UTC)[reply]
  • I'd say that you should not apply {{furd}}. First, a human should compare the images to make sure that no technical bug caused a significant change to the image as displayed. Second, taking your example image above, the original uploaded already made an editorial decision to use only a fragment of the true original for the image. That editorial decision is a creative act, so it doesn't seem appropriate to eliminate that authorship history. Is there already a better template that indicates that human evaluation is required? If not, I suggest creating one and using it instead. I think the main thrust of the bot task is reasonable. GRBerry 19:29, 17 March 2008 (UTC)[reply]
    • OK, thats reasonable, I would hope the admin would confirm with the furd, but I can see your point. If someone wants to make an alternate template, please do so, as I suck at templates. XD As far as the reduction goes, that image is clearly too large. We can easily reduce the image size to no effect at all on the article proper. Unless I'm missing something of course. :) Edit: I should be a little clearer, the program's reduction of the image size in this case will not affect the article at all, see Logarithm#See_also, look to the right. —— Eagle101Need help? 19:33, 17 March 2008 (UTC)[reply]
      • Ok, replying to self, I think I picked up why removing the original is bad. We lose the authorship history. A good way to prevent this would be to perhaps have the bot put those details in the description. Is this a possible answer to this concern? Sorry that it took me a second to realize what you were getting at ;). —— Eagle101Need help? 19:41, 17 March 2008 (UTC)[reply]
  • I don't see any reason why we'd need a huge image, but I would suggest creating a template that you make known to existing users to include on an image page as part of the rationale of why they need an image that large for non-free works. (Technically, this would help us further machine-readible-ize our NFCs, by saying that any image over a certain number of pixels will have the potential to be reduced unless this template, which should include a more descriptive reason for the large size, is included). Then the bot should ignore such images, though I'd recommend that any image that is tagged as such should be looked at closely by an admin and evaluated if the rationale is sane. --MASEM 19:39, 17 March 2008 (UTC)[reply]
    • Yes, that is a possibility. However I'm hoping to stick to images that are large enough that there really is no reason for a larger image. Remember fair use images only need to be good enough for the article, we don't have to have a higher resolution available. As far as I understand, its better that we don't. If you can elaborate, please do. I also welcome someone actually creating this template and linking that template :). —— Eagle101Need help? 19:43, 17 March 2008 (UTC)[reply]
  • (after many edit conflicts) I am not convinced doing this without an editor request to shrink the image beforehand is a good idea. What about a large non-free image with a very specific rationale that explains why that level of detail is necessary (I could imagine there are pictures over 600 x 600 that includes such a rationale)? Are you prepared to dissect that information in the multitude of ways it could be presented (templates, non templated, etc). I would be more comfortable with you creating a template (or using a variation of {{Non-free reduce}}) that would basically have a human say, this needs to be reduced (maybe even input a size) and have a bot just do the dirty work (you could also add the {{furd}} when you are done, because an admin will have to visit the page to delete the image anyway). Also, what size are you planning on uploading the images at exactly (are you always using the thumbnail size)? For example, I would reckon that your could scale down any album cover to say 400px by 400px (probably even smaller). But if I am reading your proposal correctly, they would most likely end up at varying sizes. Also, is there a reason you have chosen not to use the standard BRFA template? I think the bot task has a lot of merit, I just think some of the details should be hammered out a little more before letting it loose.
