How to Fix Image Rename after processing?

I am doing webp image processing but image rename ugly. I want the exact file name or the resize dimensions only.

Original Name:

Processed Name:

How to Fix this?

There is currently no simple way of doing that (I have mentioned in another thread a workaround using resources.Concat, which I guess would work in this case to), but it’s on the road map (but no-one have implemented it) to add a simple “rename” function.

yup I’ve seen in this thread. but didn’t understand.

Can you please elaborate. How to fix and do this
