Fixing sprite offset?

[TuomasGaming]

I just want to know how to fix the offset in the sprites I'm making for a personal DOOM mod.

 

Yes, I have tried the "Optimize PNG" button, and it didn't do anything.

In Slade, use the highlighted settings. Or you can drag the sprite directly with your mouse, the lines tell you where to put it.

You can select a lot of lumps at once in Slade, right click the selected batch, click "Modify GFX offsets" and then click the preset for monsters or weapons as well, this gives you a great bases to work with (always seems to work perfectly for player and monster sprite replacements especially).
