Microsoft powerpoint has graphics interchange format so you can get jpg’s of pictures in the file.
Lib Off should have the same option.
I’m not sure that MS “has” GIF.
What specifically is your proposal? I expect that even those who have Powerpoint (and not everybody have) would not understand how to see this function based on your “description”.
FYI: LibreOffice can export “pictures in the file” by right-clicking on them and choosing “Save”, and also you can export selection to a raster format using File-Export.
