want to change direction of "Strip of Images"

[Seeker]

for example

00.jpg
01.jpg
02.jpg
03.jpg
04.jpg
...

Strip of images > mosaic > Number of thumbs per row 2


new image will be left-to-right

00 01
02 03
04 05
06 07
...



but I want right-to-left

01 00
03 02
05 04
07 06
...


I want a option that can set direction, ltr or rtl.

thanks.
