Shape Layer : Repeater : Same distance Scale

It's been a while, but for people looking for the answer for this and stumble upon this forum post, use offset path instead of repeater. 

Rick what would you sugest if I wanted to repeat a png 10 times with no space inbetween. I can do this with a repeater but what I really want to do is this...

I am working with 42 brands of shampoo and have 42 differnt product pngs that I have sized via a photoshop action to all have the same height of 1000px and a Variable width based on the type of bottle (so some are 400 px while others are 100 px width). I have writin code that will swap out the png file and redner the same animation for each 42 shamppoos the issue I am running into is that bc of the variable width some have space between them and others do not and I would like them all to have no spaces between them. Do you have a sugestion script or expression that could set the offset of the repeater to match the width of the png?

I can't seem to find how to create a repeater that scales the copies while keeping the same distance between them.

That's not possible. By its nature scaling is not a linear transformation. As the others suggested already, construct the shapes manually. Depending on what you actually want to animate, you may also consider the Radio WAves effect to produce your concentric circles with controllable spacing. If you tweak the settings for wave decay and speed just right, this could totally do the trick and as one of the few vector-based effects, it should just be as sharp as using shape layers.

Start with a single parametric Shape. Then duplicate and offset its size - repeat the process and ensure the size reduction is consistent across all duplicates. I doubt you'll get the Repeater to provide symmetry across its Copies, in the manner you want.
