Hello,

its easy .. just try to find how iPad sorting the images, what is the logic, you will find that the photos titles should be 01,02,03,04,05,06,07,08,09,10,11,12 ..etc and not 1,2,3,4,5,6,7,8,9,10,11 etc . in this case iPad will sort it like this 1,10,11,2,3,4 ... etc

1st of all you have to ensure that the date sequence is right, iPad sorting by date then by title. so in case your photos have random dates open photoshop and update them all by batch update.
