I am new to the process of making maps, and I have run into some difficulty using the images I made to make the base of the map. I am using Gimp and have tried both using BMP and PNG files and still am unable to use them in WorldEd. In addition, I do have a _Veg layer present and have made sure that both the non-vegetation PNG and Vegetation PNG are both present in the folder since I have seen that in previous threads. I can attach my files if wanted, and thanks for any help!
