+#### GetItemTexture(displayInfoId)
+Returns the texture path for an item given its display info ID. Returns nil if the texture is not found or is the question mark placeholder texture.
+
+**Parameters:**
+- `displayInfoId` (number): The item's display info ID (can be obtained from `GetItemStatsField(itemId, "displayInfoID")`)
+
+**Returns:**
+- The texture path string (e.g., "Interface\\Icons\\INV_Sword_04"), or nil if not found
+
+**Examples:**
+```lua
+-- Get texture for an item
+local displayInfoId = GetItemStatsField(19019, "displayInfoID")
+local texture = GetItemTexture(displayInfoId)
+if texture then
+    print("Texture: " .. texture)
+else
+    print("No texture found")

+
+#### GetSpellTexture(spellIconId)
+Returns the texture path for a spell given its spell icon ID. Returns nil if the texture is not found or is the question mark placeholder texture.
+
+**Parameters:**
+- `spellIconId` (number): The spell's icon ID (can be obtained from `GetSpellRecField(spellId, "spellIconID")`)
+
+**Returns:**
+- The texture path string with `Interface\Icons\` prefix (e.g., "Interface\\Icons\\Spell_Frost_FrostBolt02"), or nil if not found
+
+**Examples:**
+```lua
+-- Get texture for Frostbolt
+local spellIconId = GetSpellRecField(116, "spellIconID")

 #### ChannelStopCastingNextTick()
 Will stop channeling early on the next tick if you have queue channeling spells enabled and try to cast a spell before the next tick (didn't know how to cancel channels without casting another spell).  Uses your ChannelLatencyReductionPercentage to determine when to stop the channel.
