These are already in-game for displaying in a texture region eg.
Lua Code:
local f = CreateFrame("Frame")
f:SetSize(50, 50)
f:SetPoint("CENTER")
f.Texture = f:CreateTexture()
f.Texture:SetAllPoints()
f.Texture:SetTexture("Interface/Minimap/Vehicle-AllianceMagePortal")
You can preview them by going to
https://wago.tools/ and searching the files for
Vehicle-AllianceMagePortal etc.
You can also export the art files form the game and convert them to .png using
https://wowinterface.com/downloads/i...7-BLP2PNG.html
or
https://wowinterface.com/downloads/i...Converter.html
Exporting also gives you their relative folder for use in-game eg. the Vehicle-AllianceMagePortal.blp file will be in the
Interface\Minimap\ folder.
