I am very new to this forum and have joined because I have undertaken a huge learning curve in graphics.

I have created graphics in PSElements which are transparent. I have loaded them to a slide show, which seems to be the only way to create a PDF through PSElements.

Everything stays transparent to this point.

Then I output to a PDF and when I open the PDF they have backgrounds again, even when I open in PhotoShopElements.

Please help with this problem
