Building new game interface

Hi. I would like to ask if anyone knows a way to modify the attacks tooltips. You know, when you have a unit selected, and you put your cursor above his 'Attack Type' icon, you have a little description. That's what I want to change... 8)

For example, if you click on Tichondrius. He has Chaos Attack Type. You have written details on his damages, range, rate of fire, and... explanations on his Attack Type. "Chaos attacks do full damage to all armor types." it says... This is precisely what I want to modify. Anyone has an idea on the file to modify ? :cuss:

I also have another problem. In addition of modifying the 'Attack Types' tooltips, I would like to modify the icons... For that, there's a 'Game Interface' menu in World Edit to easily modify it. So, I wanted to add customised icon for Chaos Attack Type. I create my icon under a *.bmp format, I convert it into *.tga format, then I use Wc3 Image Extractor II to convert the *.tga into *.blp, and I import it into my maps via the Import Manager. Now, I get back to the 'Game Interface' menu, change the picture of the "Chaos (No Upgrade)" line, and I save. I run the game, and select a unit with Chaos Attack Type, but... no picture... :bangH:

I tryied a lot of things, like exporting a same-sized picture, and directly importing it into the Import Manager without any modification, and it worked. It appared that the Wc3 Image Extractor doesn't correctly convert picture into *.blp...


Anyone can help me, please ? :...:

First of all, the probelm is as follows: It doesn't have an alpha channel. The Bmp file doesn't jave one and didn't add one when it was a tga. Every icon NEEDS (I don't know WTF blizzard was thinking when they made this restriction) a blank alpha channel for some reason. Also, is your image 64 pixels by 64 pixels?

And how can I add Alpha Channel ? Do I have to create my icon under a specific format, or create it with a specific program ? Is there any way to solve my problem ?

edit: Indeed it was 64x64 !
