It's not a good idea at all to work directly in the Edge js files - there's a very strong possibility that you'll mess things up, rendering the main project file unusable/very dificult to recover.
As to the "eid18", it's a restricted Edge id - definitly not to play with.
I have like 100 photos i dont wanna animate it manual all.
Is there other way, pls light me and very thanks for ur reply.
There're always automated ways for doing that sort of things but I think it will take some pretty complex bit of code (beyond my knowledge). You can wait for other folks to help or you can go straight to the manual way - if the animation is the same for all 100 photos, then this is how I would do it:
1. (I only have 1 photo animation) Copy/paste transitions data 10X (now I have 10 photo animations);
2. (I have 10 photo animations) Copy/paste transitions data 10X (now I have 100 photo animations);
3. Edit the XXXXX_edge.js and locate the photo ids and replace the file names - one of the safe ways to directly edit an Edge js file (nevertheless be very carefull).
