Let's make textures - Errors in Paint Shop Pro 7 (part 1)

I will start showing the errors first, to see what not to do.
First, when you put your plugin in your folder :
Jasc Software Inc\Paint Shop Pro 7\Plugins\Formats
The plugin, which works for Paintshop pro 7 (PhotoShop .wal plugin) :
tastyspleen panjoo
Or get it from below, but copy the download link in https://archive.org/ (PhotoShop .Wal Plugin):
quake2.com
Another place :
idgames2
.pal file goes to :
Jasc Software Inc\Paint Shop Pro 7\Palettes

Saving a png file using Paintshop pro 7 save to wall (palette applied with Pixly)

Opening .wal file with Wally or with Quark editor, shows the texture wrong.

Making a image from scratch with Pixly with Quake 2 pallete, shows wrong ingame when saving as wal trough Paintshop pro 7.

If you take a image made with your camera or phone and save it as a wal file trough Paintshop pro7 it will look good sometimes.

This is how the image should look
