A method to automatically optimize all PNGs in a folder
This should be equivalent to running PNG Monstrous with the pngout and zopflipng options enabled. This script requires zopflipng, pngout, and GNU Parallel. It will run pngout and zopflipng on all PNGs in the current directory and output the optimized images to the ./optimized directory (only if the resulting file is smaller). Zopfli uses the  (" ") and   (" ") options. It will compress multiple images in parallel, up to the number of CPU cores in your computer. You will also need to download pngout from the AUR or manually and place it in your PATH. Zopflipng and parallel can usually be installed with your package manager.

Getting Screenshots from Wii U
In the past, it was possible to get screenshots from Wii U games by accessing the Wii U's internet browser during gameplay and uploading images to Dropbox or a site like Imgur or Postimg. However, these sites now use newer web standards that are not supported by the Wii U's browser, so they no longer work on the Wii U. However, after reading through Reddit posts about it I found a way to get screenshots to your computer using this HTTP file server software. You must run the program, set a target directory for files as described in its instructions, find your computer's internal IP on your network, and access that IP from your Wii U browser, where you can upload the images straight to your computer. It uses older web standards (for now at least) that are supported by the Wii U, and it can run on Wine on Linux/MacOS.

In addition, it is still possible to upload straight to MarioWiki from the Wii U if no cropping is required on the computer.

Some common confusion about SMG/2 images
To clarify some definitions: upscaling isn't the same as rendering above native resolution. An image is upscaled when the file's resolution is higher than the resolution of its content (for example, when a game is rendered at 1x native resolution but screenshot in Dolphin's full screen mode, or if the image is artificially resized with an image editor.) This causes unnecessary file bloat and should usually be discouraged. However, this is not the same as setting the emulator to render above native resolution (in multiples of the native resolution via the Auto setting in Dolphin.) This produces images whose actual content is in high resolution, and thus does not waste file size. According to 's screenshot guide, it is acceptable to capture Wii screenshots above 1x native resolution due to Dolphin's inconsistencies with producing native resolution screenshots without upscaling or stretching (read that guide for more info). For SMG/2, I follow that guide to produce 1920x1048, above native screenshots. I usually replace an SMG/2 image if:
 * Its aspect ratio is not a multiple of the game's normal widescreen aspect ratio, such as 1920x1054.
 * Its unnecessarily upscaled (e.g., rendered at 1x native but taken in full screen mode).
 * Its not an emulator screenshot (e.g., from a YouTube video).
 * I can get a better view of the subject

Tricks with imagemagick

 * Using, it is easy to stack two or more images vertically using the command . See left side for example.
 * It is easy to crop images (such as artworks) to their content (removing the surrounding solid color or alpha space) with . If there is any slight shading that needs to be cropped over, use the   option, where x is a low number (try 3 or 6 first). See below for a script to bulk trim and compress all images in a folder.
 * Similarly, it is easy to apply transparency to simple graphics, such as sprites, with, where color is the name of a color (e.g., white) or a color's hex code, enclosed in single quotes. However, more complex graphics with fuzzy edges, such as artwork, might look choppy, requiring the use of the   option or not at all. Don't apply transparency to these types of images unless it is very clean.

 * Re-encoding JPGs all the way at the 100 quality mode can severely bloat file size, while using low quality modes can cause visible artifacts. When processing JPGs, consider adding the  option, providing a better balance between quality and size. Also, consider the   option for PNGs, which removes unnecessary metadata/gamma/color profiles. However, applying PNG Monstrous or another optimizer should do this anyway.

Cropping to content and compressing with one script
This will crop all JPGs or PNGs in a folder to their content and optimize any PNGs, placing them in the  directory. The remaining  directory is the unoptimized PNGs.
