If you used Insert&gt; Object to embed an object, it's hard to tell what may be in that image (or charts or spreadsheet). Try to ungroup it (right-click it and choose Grouping&gt; Ungroup).

If necessary, you can copy and paste into an image editing program and save the image there before inserting it into PowerPoint. File handling Here are some file handling tricks that can also reduce the size of a presentation: Save the file under a new name.
