Can't see my own icons

Hi there, i really need help, because my icons don't work

I working on a campaign-project and downloaded some models
Now I need some Icons for them, because there aren't any for them

That what i did:
... made some Screen-shots in WE-Editor
... changed them with "Nero Photosnap" to 58x58, cut something away and changed them from .tga to .jpg
... opend a new Image with "Paint" (I know, it's not really good...)
... set image-size to 64x64
... made metal-border
... paste the 58x58 screen-shot picture into the image and placed it in middle
... made a copy of it and changed the border black (the DISBTN)
... saved as .jpg (paint dont work with .tga)
... made color-settings from the DISBTN to 50% (DISBTN completed)
... extracted with "Nero Photosnap" both to .tga
... extracted both with "WC 3 Image Extractor 2" to blp
... imported the files
(they didn't get their normal names, i called them "BTNTroll-Hütte" and "DISBTNTroll-Hütte" and they appear like this: "BTNTroll_H_LP" and "DISBTNTroll_H_lp")
I changed them to the right path (ReplaceableTextures\CommandButtons\BTN...) and so on

I can't show them up in WE and "WC 3 Viewer", but in "WC 3 Model Editor"
I tried with importing as .tga but they also get their strage names, their typ called "other" and ther don't work either.

May it's the Image-programmes i use,
may the XX-bit setting from the pictures
(i don't know how to show or to change it)

When you now thing, I'm a noob in making images and so on, you are absolute right ^^°

By the way: sry for my bad english,
it's not my native language

you have killed the alpha channel. it makes things invisible or teamcolor. check out the tutorials.

you also cant use and letters with silly "effects" on them like that U with points, and high stripes like this: -, you have to use the low ones: _
