Custom Tiles not showing (FIXED)

[Felis_Citrus]

Hi! Ive been trying to make an occult/ritualistic mod and ive made a little pixel art edited straight out of one of the other URW pngs. However, when i did the [TRUEGFX:] thing in the diy glossary, the graphic didnt appear for some reason. I edited the photo using preview on windows and made it using MS Paint. Am I doing something wrong?

Context: Was trying to butcher Njerp warriors for skulls for other recipes.
.Human Skull. "Stone" [effort:2] [phys:hands,one-armed] *HIDEWORKING* %100% |1| /20/
{*dead *} (1) [remove]
{Knife} <Broad knife>
[TYPE:tool]
[WEIGHT:3]
[PRICE:0]
[TILEGFX:human-skull]

Also, if anyone has a fix, how do i change *dead * into something less clunky like "Dead body"

Edit: Don't know why, but when i renamed the item from "fels-huskull" to "human-skull", the graphic worked.

Edit 2: Ok, it seems to me that the game doesnt register new Truetile files until its restarted

You can use F9 ingame to reload truetile files for easier testing purposes.

Also, i used a 66x66 tile size for making "statue" buildings (heavy items with big graphics to simulate a structure, while it is actually an item)

However, while the graphic has the desired effect of taking up 2 vertical tiles to emphasize height, the graphic is anchored on the top half instead of the bottom half.

Is there a way to adjust the position of an item, or control whether the graphic goes up or down?

Attached is the graphic I'm using
