Currently I’m creating an action but if I use the same action on a bigger image for example, the effect it needs to create is destroyed. Is there any way to create an action that affects all image sizes?
Depending on the action, yes. But generally, if it is an action that works based on pixels, sizes and margins (i.e. create masks based on the size of the canvas), then no.
I’d suggest you offer different variations of this action for the different size ‘groups’. You could take my latest PRO Actions item for example; there are about 2-3 actions which are size-dependent, and therefor I had to offer a few variations.
Here are a few resources:

Thanks a lot for the information! Scripting won’t help much as I’m a total n00b when it comes down to code.
