Offline editor 2-bit
 

Does offline editor not except 2-bit images as images for an npc?

Why don't you just try and see what happens.

It usually lets you use any graphic as long as its not using actual black.

It doesn't let you use graphics higher than 16 bit [I think]. 2 bit will work. Anything will work as long as its under 16. However, if you have a server, you can use higher quality images.

i did.... and the 2-bit img didnt work... i was confirming, thanks

ohh i think it's because I used actual black

You can edit it as 16
