I recall Photoshop cs3 had "audio annotations" Now looks like it doesn't . I wonder would It still be possible to open and listen such annotations in current Photoshop from files saved in cs3 one? I need to do a lot of annotations for a lot of images and kind of tired of pushing buttons. Was those audio clips kept inside psd files?
And how could I activate cs3? I still own a box but It's not even same computer now.
CS3's activation servers have been taken offline, so you won't be able to install or use it. In fact don't.
Take your serial number here: Activation or connection error when starting CS3 or Acrobat 8
and you will get a non-activation installer and a new serial number to unlock it.
As for audio annotations, they were removed in CS5. So I guess there is no way to read them unless there is a plugin or extension out there.
