Powerpoint graphics - Compress Pictures

[Soriah]

HELP!

I have a presentation (2007) that has several CADD-type graphics that were
saved as .PNG imported onto some of the slides. To make the presentation as
small in size as possible, I used the Compress Pictures feature to reduce the
size of the graphics. After using that feature, I looked at my presentation
on my computer screen and on the screen in our conference room, and noticed
there's a line to the left or bottom of each picture that I can't remove. I
even tried to crop out the lines; however, they still show. As a test, I
opened one of the pictures in Photoshop, saved it again as a .PNG, pasted it
back into Powerpoint, and voila!, the line was gone. Is the problem with
"Compress Pictures", or is there something else I'm doing wrong?

If there is a bug in "Compress Pictures", I suspect that it has something
to do with the vertical resolution of the graphics - the compression
algorithm somehow messes up the last line of pixels. I would try resizing
the original images so that the vertical number of pixels is divisible by
16 - for example 960 instead of 1000 pixels - perhaps that would help the
compression succeed.
