Cardmerge

  • Build multiple 4×3 split cards (left and right halves in one image).
  • Batch upload maps files in order: 1st, 3rd, 5th… → left; 2nd, 4th, 6th… → right.
  • Each consecutive pair fills one preview; extra previews are added automatically when needed.
Files pair into each preview: odd positions → left half, even → right. Extra previews are added automatically.
