Transparency fail on the KS Editor Mod?

I'm using Looki's KS Editor Mod, and the transparency decided to break on me. I dunno why, but if I make a tileset from scratch, it won't transparencify on the KS Editor Mod. :< So this is both a help topic and a tileset release topic, 'cause I haven't released the latest (and final!) version publicly yet. The tileset in question is attached.

EDIT: Also, I tried the Patronizingly Simple Transparentizer, and it froze after I tried transparencifying it.

melikes the tileset, very nice re-interpretation! BTW, try the attached version. i transparent-ized it in PhotoShop

EDIT: just noticed the black outline on the blue pipe is a little screwed up. don't have time to fix it ATM

ZOMG you finished the tileset lol dies of laughing the end

noob pumpkinbot can't transparency. Very nice tileset, I demand a great level from you with this!

No, noob Level Editor Mod can't use transparency. I can do it in GraphicsGale and Windows even says it's transparent, but it usually has either a magenta, black, or white background.

And I just thought of using Iaza.com to transparencify it. *headdesk* Let's see if it'll work.

EDIT: Iaza made it transparent, but, for some reason, the LevEdMod won't recognize it at all. :<

Eh... your attachment isn't transprent, Pumpkinbot.
Both KS and the editor will either use the alpha channel, the PNG's transprent color or #ff00ff if there is none set.
But your image uses white as background.
I didn't change any of the related code..
I really don't know why it should be working in the first place.

*facepalm* I know it's not transparent. Yes, I've tried magenta 255,0,255, and it didn't work. I've tried setting the layer transparency to magenta, nothing. Frame transparency to magenta, nothing. Neither as transparency, nothing.

EDIT: Okay...I have no idea what I did, but I made it transparent. Whatever, I'll post the tileset in my tileset thread, if I can find it...
