I have NO idea what you are talking about...Are you sure you mean something in InDesign? Maybe an Animation? Or Overlay?
Image sequence for WHAT? They only work in DPS.
Do you mean something you produce in Adobe Muse?
I am also trying to figure this out. In the past, one of the "folio overlay" cool things to do was to have an image sequence in a folder and, and you could preview controlling it by swiping. It was really cool, but that was before the "publish online" option was built in.
The "publish online" option now seems like a great way to distribute a catalog of products that i will be working on -- along with a for print version -- and I was hoping to include the 360 degree image sequence of some products. But now that image sequence option is missing from the "overlay" panel.
Perhaps a "slider" type control of a movie? That would let one advance or reverse the movie, frame by frame...
I feel a bit "out of the loop" on knowing the newest features of InDesign, and find so much outdated help online.
The Overlay Panel is for DPS/AEM only! It does not work otherwise, so it is of no use for Publish Online, FXl ePub or other 'interactive' documents.
A build in alternative for Publish Online/FXL ePub for swipes etc is NOT available in InDesign, you will have to do this in HTML5...
