Here is the example to avoid black background:

src="/uploads/phpThumb.php?src=images/expressionengine_logo.png&w=100&f=png" 

src="/uploads/phpThumb.php?src=images/expressionengine_logo.png&w=100&bg=D4E9F7"

Try replacing ImageCreateFromJPEG($file) with ImageCreateFromPNG($file)

Most probably this is the common error for the black background in the resized pngimage

Well, I am not familiar with PHPThumb but you can use SimpleImage library with this update.

I am using it and didnt faced any problems yet. This library has purposefully updated for the problem you are facing right now. Go to the links and try to use it.
