I see people using silly filetypes for quests or compression on gifs sometimes, so I decided to make a basic guide since using the right filetype can easily cut the filesize in half for some images.

32-bit PNG: This high of a colour range is ridiculous and should rarely be used for the huge filesizes it has.
24-bit PNG: Usually the best if you really want your images to have no JPEG artifacts.
8-bit PNG: Black and white images, images with low colour ranges, and images that are not anti aliased are great for 8-bit PNG. Some images could suffer from using this by becoming more jagged. (8-bit PNG is the exact same as a static GIF file)

JPEG: High colour ranges are good for JPEG. You usually want around 90%~ quality for a decent filesize.

GIF: See 8-bit PNG for static GIFs.
Animated gifs are the most often done wrong, and an animated gif done wrong can make the filesize obscenely larger than it should be.
Use GIF Movie Gear for animated gifs, it is easily the best program for making and editing animated gifs. An optimized gif can shave massive amounts off your filesize, allowing you to use larger resolutions for your gifs.

Gif Movie Gear is very intuitive, but here's a good guide in case you are a grandmother or something.

I'll have to agree on GMG as one of the better progs for animated gifs.
And for the file-sizes, any decent image editor should have some kind of option for compression optimization during file saving. Look for that.

I keep forgetting to optimize my .gifs. GIMP has a .gif optimizer as well, although I can't attest to how well it compares to GMG.

It doesn't really compare. It's a lot better than nothing but GMG was made for GIFs and it shows.

The image is a joke because the original image was like 150kb or something as a PNG and looked exactly the same as the 35kb JPG.

I just use SAI's default for PNG saves. It works relatively okay. Using a fancy program to optimize would add 1-2 minutes to each update.

I guess it'd make sense for After Quest, since those files could get pretty huge considering how small the actual panels were. Tozol Quest's files are already smaller than the thumbnails, though...

Most image programs I have worked with offer at least the basic options for choosing bit, and if not GIF is the same thing as 8-bit PNG. Optimizing with another program is probably overdoing it for a static image (Going over some options in PNG compression make it clear that the gains are not very significant, topping off at around 10% reduction in size for a time sink of over two minutes for the best compression.)
Tozol is already using 8-bit PNG which is one of the best things you can do to keep filesizes down already.
AfterQuest pictures seems to lose nothing going to 8-bit but the filesizes remain pretty large, going from 280kb to 180kb on some. Some people are highly against jpeg because it isn't lossless but I don't see quest images as needing a lossless format for the readers and the quest creator could always keep original resolution PNG files if changes need to be made after uploading.
JPEG takes one of AfterQuest's images from 280kb to 80kb with no loss visible at 100% zoom. The less sharp and contrasting your image is the less suited it is for PNG.
