Convert to .blp?

Does anyone know how to convert a file to blp? I made a skin but don't know how to.

Try Warcraftiii image extractor 2...go to downloads, its supposed to be top1 downloaded tool.
open your .tga skin, or wathever it is, and save it as a .blp, as simple as that.

Errr... You can't since you need an mpq file and if I open the WC3 one I won't see my skin...

Use Yobgul's converter. Also converts BLP to TGA and vice versa.

Make sure you got Image Extractor II (v2.0). There IS a menu Open->Image (where "Image" is just below "Archive MPQ"). Try Ctrl+O. It allows you to open TGA or BLP. Then, there is a "Save" menu. Just specify which extension you want to your file, append it and save. Done.

I suggest to use Warcraft III Viewer. It provides much more features than WC3 IE 2. Since you are a new user I suggest to start off with it.
There is a thread in this forum, which provides a download link.
