Plan a batch image resize and rename workflow

Task: Plan a repeatable workflow that resizes, renames and exports a batch of images without touching the originals. Context: I have about [number] images in [format] with sizes around [dimensions or file size]. They must end up at [target size, format and file size limit] for [website, email, print or social media]. I want names like [naming pattern]. I do this about [how often]. Rules: - Give at most seven steps and say at which step the originals are copied, so that no step works on them. - Include a check on five sample files before the full batch, and a final check of the count and the sizes. - If a step uses a command line, script or settings change, explain what it does in plain words before I run it and warn me about anything that overwrites files. - Do not claim what a specific image tool can do. Describe each step by the function needed and tell me to find it in my own tool. Result: A numbered workflow with the check after each step, followed by one line on what to save for next time.
