What happened to my image? (pics)

[Lights Out]

I created the above image using Photo and Graphics 9 and saved it as a PNG file.


I added this image to one of my webpages in Sitebuilder, my yahoo web designer. It looked just like the first image in the design tool. When I uploaded it... well, you can see how it looked below... What happened? The original image had a nice fade effect that extended well beyond the text. What actually appeared on my website shows no fade effect, just a harsh edged photo under the text. ???



I loved the way the image saved (first pic), but am really disappointed in the way it loaded to my site. I saved the second pic as a jpeg with my snipping tool from my actual website.
