Feature requests, Add Image pager & few validations

Problem/Motivation

hello and thanks for this great module.
when i was using it i run into some things which would make this module even better :)

1. when using the pager, it would be nice, when there is onle 1 image, that it doesn´t show up.
2. the possibility to use also images/thumbnails as pager
3. the setting that you can pause the slideshow from the beginning and just move to the next picture when you click the pager or prev/next
4. translation possibility - i think "prev / next" is not possible to translate threw the drupal translation surface function

greets
