Replacing Paintings (Pre-2.21 Versions)
The following is a list of painting names by their block size for pre-2.21 versions. To replace a painting, follow these steps:

1. Unzip both packs and locate the section corresponding to the size of the painting you want to replace in Alt_Paintings (e.g., 4x2 blocks).
2. Identify a painting in that size category (e.g., "4x2_Sapling").
3. Rename your replacement image to match the name of the painting currently in Stardew_Paintings (e.g., "4x2_Sapling" -> "fighters").
4. Place the renamed image in Stardew_Paintings, zip the folder back up, and your new painting should appear in-game.
