many thanks for your comments on PDFAnim.

I've also been looking but as no other solution was available
I had to create PDFAnim :-)

What do you mean with problems?
The ones I know are:
- Bad/slow rendering of animations (it's up to ADOBE to improve this :-)
- As soon as you click on an animation keys as page up/down or enter
don't work anymore. This is because the clicked animation gets the
focus and thus all pressed keys are send to it - also not evaluated
in any way :-(
To get keys working again click somewhere outside of the animation to
give the focus back to AcroReader.
If there are additional problems please let me know.

A PushButton is used for the animation. As far as I know
it only evaluates a mouse-click inside the button.
Pressing enter or space key while the button has the focus gives
just the same result. No other actions (like right mouse click or
back-space key) are evaluated. Please someone correct me if
I'm wrong 'cause I would like to implement this feature.
From my point of view the only way to implement a backward step would
be a separate "backward step" button (not my preferred solution).

I totally agree. I just did't find the time to implement this.
Will be in one of the next updates.

I'm not shure. At least not without a considerably amount of work.
An included .pdf already contains all necessary information to be used
as icon for a PushButton. These info seems to be missing when trying
to use .jpg or .png.
At least I couldn't get these formats working: They
can be imported the same way as .pdf but not be used as
icons for a PushButton.
As there are many programs out there to convert .jpg or .png
to .pdf and thus creating the missing info (more or less not even
changing the filesize 'cause .jpg and .png are file formats supported
by PDF) I don't think it is worth to spend much more time on this.
