Adding Sequential Numbers ON Pictures

The Julieanne Kost video is great.
However, creating vector based items such as tickets, etc would be more correctly performed using variables in inDesign. Photoshop can be used to create tickets — but InDesign is the correct tool to use.

If you have InDesign, that would allow you to achieve what you want.

You would need to use Photoshop scripting actions can not do what you want to do. You could print them on roll paper with a script like my paste image roll or build that process into your script. Create large documents with many sequenced tickets laided out in them. The steps are the same steps yod would use in an action however you can use locic to update the sequence number in the setial text layer and position the tickets location.  You need to code in one of three supported scripting language. Javascript is the best choice. you fo not meed to have a dialog like pasteimagerollm Rou most likely want to have a ticket template file that your scrip opens and loop update its serial and paste mintp pace into your print document.  You can look at my pastimageroll script to see how to tile you ticket image into a document.
