Compress pictures on Excel 2004

Yeah, it's me again with yet another Excel question :p
Anyway, does anyone knows if it's possible to compress pictures on Excel 2004 and how?
My files are getting too big even if I resize the pictures to 320x240 before adding them to the file, so I want to compress everything inside Excel, if that's even possible (I've read online it isn't...).

I don't know if it's the same with Excel, but with Word if you do a Save As it may make the file size smaller if you have been making changes and Saves for a while to a file. It keeps a history of changes you made which may bloat the file.

Nops, at least I couldn't find it...
I can 'print' as compress PDF, but what I want is a compress .xls

Try this.

Never mind. That's only for 2010. My bad.

And it's for Windows, right? :p

Hey, I tried to help. So sue me.

LOL

Leave this to the professionals. Go back to your drawin' and stuff.

Hack. :p
