==Image color-correction documentation==
*'''Suggestion: Use the term "color-correction metadata" rather than "gamma brightening," since gamma is technically only one of several pieces of metadata (ICC profiles seem to be the most common) that affect the color of the image and could be removed by optimizers.'''
*'''Can someone with a Mac verify whether the below procedures work for ImageOptim?'''
*Maybe someday when I have more time I'll build a better utility to implement pngout and zopflipng. It doesn't seem too difficult
===PNG chunks===
PNGs can contain four ancillary chunks with colorspace information<ref>http://www.libpng.org/pub/png/spec/1.2/PNG-Chunks.html#C.Anc-color</ref>, which may affect the way software displays the colors in an image:
*gAMA - determines color intensity
*cHRM - determines color chromaticity
*sRGB -
*iCCP -
While most images do not contain this metatdata, if it is present, these chunks should be preserved to ensure that browsers display the image's colors as intended. Images that were originally exported from the Adobe suite or other specialized software (such as artwork and press images) seem to be the most likely to contain color-correction metadata, while emulator screenshots likely do not contain such metadata. Most optimizing utilities (such as [[User:Wildgoosespeeder/PNG Monstrous|PNG Monstrous]]) remove this data by default, which can be problematic.

===How to safely optimize images that contain color-correction metadata===
It is possible to keep certain metadata, such as the gamma chunk or embedded ICC profiles, while still optimizing the image. [https://imageoptim.com ImageOptim] on macOS should support this option if you disable <code>Strip PNG Metadata</code> and <code>Strip JPG Metadata</code> in Preferences. Otherwise (for Windows and Linux), If you are familiar with the command line and willing to use it, you can do this by manually running the actual PNG optimizer from the command line and passing the appropriate options. For the best compression, run <code>pngout</code> then <code>zopflipng</code>, but running only <code>zopflipng</code> is probably good enough in most cases. After optimizing, '''please verify that the colors of the new image remain the same.'''
====Installing the command-line tools====
*Linux: Install <code>zopfli</code> and <code>pngout</code> with your package manager.
*Windows:
**[http://advsys.net/ken/utils.htm Download pngout for Windows]
**zopflipng: TBD
====Zopflipng====
Example command to preserve important chunks:
<code>zopflipng --keepchunks=iCCP,gAMA,cHRM input.png output.png</code>
See [https://github.com/google/zopfli/issues/113 this page] for further explanation.
====pngout====
Example command to preserve important chunks:
<code>pngout -kiCCP,gAMA,cHRM input.png output.png</code>

==Gallery Sorting==
<gallery showfilename=1>
I have made a simple Java program/script to automatically sort galleries alphabetically. It is now [https://github.com/tsweet64/mariowiki-editing-scripts on GitHub] if anyone is interested. However, please note that I have not extensively tested it, and if you use it, you should double-check the result to make sure nothing was removed/broken in the gallery. Please tell me about any bugs. Also, feel free to tell me about any gallery sections that need alphabetical sorting below, and I will take care of it:
