how to use UI "image"?

[EKzyis]

Hello there

I can't find any tutorial about how to make it possible that the UI has an image around it? 

The .png I am using in spriter is attached.

Thats my code:

local assets = 
{
	Asset("ANIM", "anim/toolrack.zip"),
	Asset("ANIM", "anim/ui_toolrack.zip"),
}

prefabs = {}

local function onopen(inst)
	if not inst:HasTag("burnt") then
		inst.SoundEmitter:PlaySound("dontstarve/wilson/chest_open")	
	end
end 

local function onclose(inst) 
	if not inst:HasTag("burnt") then
		inst.SoundEmitter:PlaySound("dontstarve/wilson/chest_close")		
	end
end 

local slotpos = {   Vector3(0,49+32+8+4,0),
                    Vector3(0,17+4,0),
                    Vector3(0,-(47+4),0),
                    Vector3(0,-(79+32+8+4),0),
					Vector3(0,-(111+64+16+4),0)
				}

local function fn()
    local inst = CreateEntity()    
    inst.entity:AddTransform()    
    inst.entity:AddAnimState()    
    inst.entity:AddSoundEmitter()  
    
    MakeObstaclePhysics(inst, .3)
    
    inst.AnimState:SetBank("toolrack")    
    inst.AnimState:SetBuild("toolrack")    
    inst.AnimState:PlayAnimation("idle")
    
    inst:AddComponent("inspectable")   
    inst:AddComponent("container")
	inst.components.container:SetNumSlots(#slotpos)
	
	inst.components.container.onopenfn = onopen
    inst.components.container.onclosefn = onclose

	inst.components.container.widgetslotpos = slotpos
    inst.components.container.widgetanimbank = "ui_toolrack"
    inst.components.container.widgetanimbuild = "ui_toolrack"	
    inst.components.container.widgetpos = Vector3(0,200,0)
	inst.components.container.side_align_tip = 160
	
	
	STRINGS.NAMES.TOOLRACK = "Toolrack"
	STRINGS.RECIPE_DESC.TOOLRACK = "Storage for your tools & weapons."

    return inst
end

return  Prefab("common/inventory/toolrack", fn, assets, prefabs)

I think I have to do something special in spriter like typing "BUILD" if I want to create an animation for an equipped item but I can't find anywhere what

The game is extracting and atlasing the .scml-file just fine, it just doesn't show up ingame. Just a blank UI with the slots.

edit: If of any interest, the number for the vectors and the image I do have from another mod because I wanted to try out implementing ui images.

edit2: oh, and btw, this should go into DS forums not DST
