Photoshop timelapse has gaps

[jp12298391]

I have around 130 photos that I want to make into a timelapse using photoshop.  I keep trying to import them the way I see people do it online, but Photoshop keeps telling me there are gaps in the timelapse, which are clearly visible when I play it.  I have most of the photo files named simply: 1, 2, 3, etc..  Literally just numbers.  The only exceptions are a few pictures that I have words after the numbers in the name. I think this might have something to do with it but I’m not sure.  Any help is appreciated.

This will happen when you have gaps in your filenames. You can use Bridge to batch rename your files into perfect sequence.

With the files open in Bridge, Ctrl+A to select, then right click and “batch rename”
