There was a comment on the Rotation Import page, that says:
Though I was using a dump file in the correct format as explained above, SCJ was importing only the 1st thumb from the list of thumbs (16 thumbs, separated by comma)."If you have ready-made thumbs for each gallery - select 'Thumb' in 'Choose pattern:'
Note, you can add more then 1 thumb, separate with comma, Example:
http://gallery/|desc|thumb1,thumb2,thumb3"
Please advise how to correctly import multiple thumbs for tube embed (I believe grabber recognized them as flash videos).
