message: For everyone's info, I have added :commons:Template:BadJPEG to serve the same purpose on Commons, with the language of the template suitably adjusted for their policies and templates. Deco 02:52, 1 January 2006 (UTC)
thread_title: Added to Commons

message: Not that I need to right away, but if it was neccessary, can this template be added to non-JPEG images, if they have JPEG artifacts? I know there's nothing in the system to stop it, I'm just wondering does that fall into the category of uses for this template. - Рэдхот 15:54, 27 June 2006 (UTC)
replies: text: I'm not sure. On Commons I tag these differently, but this template is pretty much all we have here. You might consider using it but first generalizing the text a bit. Deco 16:45, 27 June 2006 (UTC)
replies: text: To avoid confusion I'd suggest making a seperate  template. --ChrisRuvolo (t) 20:39, 27 June 2006 (UTC)

text: When I come across JPEG artifacts in a non-JPEG image, I just tag it with , but perhaps a more specialized tag would be nice to have. —Bkell (talk) 02:52, 28 June 2006 (UTC)

replies: text: Ok well I've made  now. It really had to be made I think, so I just went ahead and did it. - Рэдхот 16:53, 1 October 2006 (UTC)

thread_title:  Non-JPEG 

message: This template currently recommends that when people replace a JPEG with a non-JPEG, they list the JPEG for deletion. I'm not sure that's such a good idea. If the original JPEG was a fair-use image, then orphaning it will be cause enough for an  tag anyway. If the original JPEG was not a fair-use image, though, its deletion will often be the destruction of important information about the history of the non-JPEG.
For example, suppose someone drew a diagram of something and uploaded it as a JPEG, releasing it under the GFDL. Maybe the JPEG underwent several revisions by various people. Then I came along and made an SVG version of the latest revision, uploaded that, and replaced all instances of the JPEG with my SVG. Now the JPEG is orphaned, but if it is deleted we lose all of the past revision history of the image (since the SVG is a derivative work of the latest JPEG, the history of the JPEG is also the history of the SVG). At best that's unfortunate, and at worst it's somehow a violation of the GFDL.
There really isn't any reason to delete orphaned, freely licensed JPEGs, so I propose we remove the suggestion that the JPEG be deleted and replace it with a suggestion to tag the JPEG with  (or better, a tag like  that doesn't imply that the image should be deleted). —Bkell (talk) 20:31, 3 July 2006 (UTC)
replies: text: Also, sometimes the conversion to SVG is not done properly, so keeping the JPG will allow other people to do a better job later. WP 23:47, 3 July 2006 (UTC)
replies: text: I've changed the recommendation so that it suggests the  tag. —Bkell (talk) 01:13, 4 July 2006 (UTC)
thread_title:  Deletion recommendation 

message: Some programs like Photoshop are quite bad at saving PNGs. Since it's a lossless format, this doesn't result in loss of image quality, but can impact on the filesize (some program retain colour information for 100% transparent pixels, for instance). Luckily, there are several programs that can be used to limit the filesize.

thread_title: PNG Compression

message: I'd like to add this, but I want to make sure it'd be appropriate: "For fair use images,  should be used in place of this template."  My reasoning is that if someone creates an SVG of a fair use image, as this template suggests, it violates #3 of the fair use criteria since SVGs can be scaled continuously, unlike PNGs.

replies: text: There are plenty of fair use SVGs out there.  Criteria #3 obviously doesn't apply since SVGs don't have a resolution.  --ChrisRuvolo (t) 16:16, 28 January 2007 (UTC)
replies: text: There is a concept of "resolution" that is appropriate to SVGs, but it's not measured in pixels. For example, I could create an extremely detailed SVG of some copyrighted thing, with tens of thousands of Bezier curves and whatnot, and that would be of higher "resolution" than a rough approximation using many fewer SVG objects. —Bkell (talk) 23:08, 23 February 2007 (UTC)
replies: text: Sorry, resolution refers to size, not quality. Fair use of SVG's resolution means that it can only be used in articles at a low resolution (and this is better than PNG because SVG is sharper). Althepal 17:40, 13 July 2007 (UTC)
