You might see that kind of effect if the background color you're trying
to make transparent isn't really all one color.
What I mean is that what looks like a white background area to us may
actually be made up of a bunch of pixels which are *close* to white but
which aren't really white. So, as a crude example, while you might have
some pixels which are colored 255, 255, 255 (pure white), others may be
255, 255, 254 with still others at 255, 254, 255.
Even that one pixel color difference will cause PPT's transparency to
not work as you expect, because it will only make transparent *one*
color -- one *exact* color -- in the image.
So you'll need to either make that background color one "flat" color in
an image editor then use PPT's transparency tool, or you need to use
the transparency technique described in the link from before.

thanks echo s-this is helpful and I've tried it -some valuable
information there.
However,
I 'mm still having problems with some images .Itried out the advice
on the transparecy tool and it worked perectlly with non-Paint images
but some don't go transpaent when I use the ppt tool but the
background or a few specks of my image do.
By the way, I do appreciate your help!
:
I think you're asking how to create transparent images to PPT. For
that, see
http://www.powerpointbackgrounds.com/powerpointgraphics.htm and
http://www.powerpointbackgrounds.com/powerpointtransparency.htm
Don't copy/paste your images into PPT. Use the techniques in the
aforementioned tutorials instead.
Further to this can I insert video clips into a ppt presentation?
Yes. Insert/Movies and Sound/Movie from File.

If I create an image with Paint or various other programmesI
cannot then copy and paste it as I want into Ppt.When I try to do
this ,even if i use a freehand selection tool, the image takes
with it a background .This means that if I want my image to be
animated the new image background obscures the original
background as it passes so the illusion is lost completely-all
I'm getting is a rectangular shape with my desired image passing
over the original background.
Please can anybody help.
Further to this can I insert video clips into a ppt presentation?
Thanks a lot.
