I do not recommend using PNG, since there is no way around to transparent in the background. My suggest to you or anyone who struggle like me....The best way to do is open MS Word and use the Insert Pictures. When it brings the picture to MS Word, you will see "Layout Options around the pictures. I would leave that alone and just right click on it to "Save as Pictures" as BMP file. Then you can go back to Styles Manager and create a new symbol and bring it in and the picture show transparent in background. This works very well.
When I cropped each image above I showed at the beginning of my post, I saved them in PNG. There was no way around to remove unless you have an image editor software or program and it does that..
For those who don't have that kind of software, then MS Word is the way to go...
Cheers,
