Batch save to multiple folders

Wondering if anyone can help- I am stumped!

I have a number of sub-folders with hi-res tiff images that I would like  to process.

Is there any way to run a batch that uses "Include All Subfolders" to process images and save to multiple sub-folders with the same name as the original sub-folders?

For example sub-folder 1 (containing hi-res images) is located here: C:\Event_Photos\hi_res\May28

For example sub-folder 2 (containing hi-res images) is located here: C:\Event_Photos\hi_res\May29

The batch would process the sub-folders and save to jpeg in the following folders:

C:\Event_Photos\lo-res\May28

C:\Event_Photos\lo-res\May29

But.. without hard coding the folder names into the script/action.

Any help would be appreciated!
