As of writing, I recommend to watch this page to notice more easily when other people add new icons.
Uploading New Icons
In-game icons are 32x32 pixels exact replica from NPC's shop or your inventory. Unequip items to remove the red border!
File name MUST be in the form Item-icon-xxxxxx.png. For example Item-icon-amethyst.png.
Because when you hover over an icon, it will display the name of the picture's file, items with more than 1 word get mushed together (ex. crabmeat.png -> shows up as Crabmeat when hovered over). A way to fix this is to give it a label tag: "icon|crabmeat|label=Crab Meat" -> Crab MeatNOTCrabmeat
Use a short generic label for generic and common icons. For example:
Use "book" not "Fire Magic: Introductory Research" since most skill teaching books have the same book icon.
Use "seeds" not "dahliaseeds" since most seeds in-game have the same icon.
(Possibly a BAD habit to do because item icons may change... just create a new file with the exact name of the item. In the above example, Dahlia Seeds have a different icon than Bluebell Seeds; probably changed since the above was written, which is probably why every item should have its own file.
In alpha there are no icons that need more than 256 color. Save the SMALLEST file size , 8 bit PNG.
Please document any new icons below, otherwise kittens die!!
Usage Notes
Using an icon
Always use the template if possible instead of the mediawiki image code!
{{icon|<icon name>}}
Icon size
Use the size parameter, for example here is Firstaid a 16x16 First Aid Kit.
{{icon|<icon name>|size=16px}}
