Compressing Pictures

[Steve P]

Using Powerpoint 2003, I compressed all the photos in my presentation using
the compress option on the photo toolbar. Afterwards, I thought my
presentation was still to big. I finally tracked the size down to a single
photo in PNG format. It seems the compress pictures option didn't help. I
did a 'save as' to a JPG format and then imported it back top powerpoint
(deleting the original) and the presentation was several meg smaller. It
would be nice to be able to see the sizes of all the pictures at once and it
would be easy to correct the offending ones.

Any comments or suggestions or did I approach this the best way?

Now I like that suggestion.
I often get presentations that are clearly far bigger than they need to be
and occasionally they are so huge that playback performance is badly
affected.
If I have the time I go through all the pictures and optimise them for size
and adjust colour balance/brightness and contrast etc. but this isn't always
possible. And often, as it seems in your case, it's just one offending
picture that takes an incredible toll on the file size.
So, VBA wizards, is it feasible to programmatically summarize the attributes
of a presentation's assets?

I'm aware that I'm hijacking Steve P's thread here (sorry, mate) but what I
mean is can you get some kind of idea of how much of the total file size
(not how many pixels) each slide occupies? That way you could quickly track
down the peskiest images. I like to optimise the images manually so I can
adjust them if necessary in Photyshop.

I'm sorry - I wasn't concentrating the first time...thanks - I'll give that
a try, sounds perfect.

 

[Steve P]

that works great!
thanks...

That's what I though you meant.
I'd try the export to HTML trick ... it'll be fairly obvious which images are
which, and if you need to manually redo them in PShop, this'll give you access
to the original images right off the bat.


That way you could quickly track
