To create icons you will begin work with your image editing software. MS paint will suffice (if it's all you have) but more powerful image editing tools like Paint Shop Pro or Adobe PhotoShop are prefered. Your finished image must be applied to a standard Warcraft III icon border.
Even for NooBs, creating basic icons is simple. Building
original and good-looking icons is more difficult.
First, be sure you are familiar with:

3b) Resize the image to 56X56, then copy and paste it into the ICON_TEMPLATE_STARTER.
To easily create Disabled or other icon types, you need Adobe Photoshop and:
4) After you are satisfied with step #3, (if in Photoshop) open the warcraft3icondocument.psd.
5) Drag the desired layer from the .psd directly to the center of your image.
6) Save the file with a new file name. Ex: BTNScarfWholeCountries.tga DISBTNScarfWholeCountries.bmp
7) Re-convert it back into a .blp.
Warcraft 3 Image Renamer is another powerful tool that performs a variety of icon editing actions.
