[edit] badJPEG?
(discussion copied from User Talk:Bkell and User Talk:Dystopos)
We do not have permission to use a higher quality version of the Tulane Shield on Wikipedia. A fair use claim is made for using the logo in the Tulane University article and specific permission was sought and received for using it in the Userbox Template:User Tulane. Neither the doctrine of fair use, nor the specific permissions granted by the Office of University Communications allow a high-resolution version to be uploaded to Wikipedia. --Dystopos 20:41, 2 February 2006 (UTC)
- The {{badJPEG}} tag is not necessarily requesting a high-resolution version. It is requesting a version in a different format. At the same resolution, a PNG version of the Tulane logo will have a smaller file size than the JPEG version, and it will be free of any compression artifacts caused by the JPEG compression. For images such as logos, maps, graphs, line art, many diagrams, and so forth, the PNG format is better than the JPEG format, for several reasons. This is what the {{badJPEG}} tag is attempting to achieve, not the use of a higher-resolution image, per se. For this reason, I have replaced the {{badJPEG}} tag on the image description page. If you have further questions, please read Wikipedia:Preparing images for upload, or post a response on my talk page. —Bkell 04:50, 3 February 2006 (UTC)
- I understand the difference in file types, but there is more to consider. The image that Tulane University provides for "web use" and which we have permission to use in Userboxes is the .JPG version as it was taken from their server. They do not offer a .PNG version. They have .EPS files for use in official publications, but we have no business offering those files to the public here. The format is quite acceptable for the sizes and purposes we're allowed. As long as no one opens and re-compresses the image again and again it should stay free of the compression lossiness characteristic of .jpg files and it is not so large that the smaller size of a .PNG would really lessen the server load. --Dystopos 05:49, 3 February 2006 (UTC)
- Note: (from Wikipedia:Fair use) "Avoid uploading fair use images in the SVG file format because it results, in effect, an infinite-resolution image, which may be harder to justify under fair use." A .PNG would certainly be defensible, but I would have to create, in effect, a derivative of a protected work in order to provide one. Since the JPG is quite ok for any use we can justify here, I think we should leave it alone. --Dystopos 06:04, 3 February 2006 (UTC)
