Unwanted borders on imported pictures

[Lachlan@FYL]

I have imported JPEG pictures to build and animate a larger diagram. When I
click on the custom animation button (i.e. before I even add animations to
the pictures), I see a thin black border on the top and left edges of each
image.

The images are regular JPEGs, but I have selected to make the white
background colours transparent using the recolour options in PowerPoint.

The unwanted borders are not removed by any of the regular picture border
settings.

How can I remove these unwanted borders or prevent them?

Are you saying aren't just some type of artifact in the edit mode, but that
the borders stay even when you are in the presentation mode (or print)?

If so, they may be on the jpeg itself, have you tried using the crop tool on
the Picture toolbar to remove the border?

 

[Lachlan@FYL]

The borders appear in the presentation mode. I haven't tried to crop within
PowerPoint because there isn't sufficient space around the picture within the
frame, but I can recreate the pictures and try this.

The weird thing is that when I import the images they're fine. When I make
the background transparent they're still fine, but as soon as save the
document or I try to animate the slide, the borders appear...??

If it's not private and you have time I wouldn't mind seeing an affected slide.

the solution to the problem with the black border on two sides is posted here:

people, please stop posting stupid answers like maybe it's a shadow, maybe it's your photos. it's never the case. someone having a problem like that checked stuff out by himself, then googled it and then posted a question. it's obviously some sort of bug and if you never saw it you won't ever fix it..

i know most of you are trying to be helpful, but figure it out whether you're useful or just crowding some thread.
