@Yukisa if the extinction of the file is .iwd you must put it in one folder outside of images folder that you created which is t6
if its .zip or .rar then you must extract it with WINRAR or 7Zip app and put all of the .iwi files in images folder
OR if its a .iwi file that you download from the forum the downloaded file name will change
So look at the file in the post that you downloaded and rename it to how it is displayed in that post or it will not show up
location still the same if it has .iwi in it goes in images folder
