When I save anything from either the internet or powerpoint, when I open it as a pdf it will have grey lines around all images when the original one has no lines.
We're sorry for the trouble you had, are you trying to Save the document as PDF or as Adobe PDF, as Save as Adobe PDF is available with Acrobat Pro, not with the freeware Adobe Reader application as the process of Printing to Adobe PDF creates a new PDF file and with the freeware Adobe Reader application, you cannot create a PDF file.
If you are trying to save a PDF, not as Adobe PDF from Powerpoint, then it is the Microsoft technology and feature of creating a PDF but not Adobe PDF, and Adobe does not have control over the resultant PDF by this methodology.
Navigate to Adobe Reader's Preferences from Edit>Preferneces>Page Display>under 'Rendering'>select Smooth Images and under 'page content and Information'>select 'Show Large images' and check
Is it possible to share a sample PDF file with us so that we can test it at our end?

Make sure that you have the latest version of Adobe Reader installed, check for any pending updates from help>check for updates, reboot the machine after updating Adobe Reade.
Let us know how it goes and share your observation.
This solution did not work for me. My source files are xml and are being transformed to XSL FO, the FO is being saved as PDF. I tried opening the PDF in Acrobat, i have the settings set in preferences listed above, saved as a new filename but the gray border stayed on the images. Can you offer any suggestions?
I do have the most current Acrobat installed.
