That's odd. Why haven't you converted the image to PNG first and after that convert it to blp.

Well, it's pretty straighforward, what are the dimensions of your image?
As for the conversion, don't worry about not being able to do that, it works fine. However, you should first convert your image to tga as it is more optimal (and you retain alpha channel as well).

JPEG does not support 32 bit. The format is only 24 bit (no alpha).

In order to get a blp with meaningful alpha channel information you will need two images, the jpeg and an alpha map (can be anywhere from 8 bit to 1 bit depending on alpha format).

Converting to PNG is a dumb suggestion as that will require re-compressing the data potentially adding loss. It should be possible to losslessly convert a JPEG image into a blp by directly moving the JPEG blocks (no re-compression). Only the mipmaps would need to be generated (JPEG does not contain mipmaps, although if it is done progressively maybe they could use data from that instead)
