Aye, there are several issues that could be affecting it ^^ Make sure your terrain follows these guidelines:
>513x513
>Grayscale Mode
>One layer
>No alpha channel
>Saved as png
A lot of art programs don't have the option to use grayscale mode, however GIMP does. Which art program are you using to make the terrain?
Also, you said you keep you custom terrains in the terrains folder, which is correct, however you need to be sure you're placing them in the folder that corresponds with your map name. Say you named your map Pridelands and saved it, there should be a folder within the terrains folder called Pridelands, and that's where you'd put the terrain you made for it.
