You need version 0.7 of the OpenGL driver for imported PNGs to work.
The interface is still.. well, you know, hideous, so I better explain how it all works
To edit a field file you need to do the following:
1. Open the file in palmer
2. Export PNG from the layer you want to edit (this will create a number of png files, do not rename any of the files, do not save files from different layers to the same location, if unsure put them in a clean folder)
3. Resize and/or edit the png files to your hearts content (but make sure you resize *all* of the files equally)
4. Open the same field file in palmer (if you closed it before)
5. Import PNG to the layer you exported from, if all goes well the display will update to show your new field background
6. Save the field file (once again, this will create a number of png files, different from the ones you edited), if you have another tool that can do LZS you might want to use that instead since palmer only writes a valid LZS file, it doesn't do any kind of compression
7. Put the png files from step 6 in the "textures" directory (from the OpenGL driver install)
8. Repack flevel.lgp with your new field file, LGP Tools will break the archive somewhat so don't use that. If you can, use this:
