SlitSlider effects

Good morning,

I have a problem with SlitSlider transition effects.

When I select a transition to attach images in SlitSlider edit from back, never change this transition effect, always is 'ease-in-out'
I check the JS code and see that in jquery.slitslider.js line 253:

When I change this values slitslider stop, only can use 'ease-out', 'ease-in', 'ease-in-out'
I want to add a pulse or other effect to my home slider.

The image has always the same effect.
Only the text messages can have another effect.

And can I change this effect with css or other JS customization?

The animation of the images are donw with CSS3 effects and can not be changed.
They allow only > vertical / horitontal
