I'd like to be able to export resized images with a watermark from Photo Mechanic.
Oh, I see. There's also an option to resize and add watermarks if you use File> Send Photos via email... or through File>Save Photos as...
You are referring to the feature for making complete websites.
What I want is an easy way to watermark one or a few images, for example if sending an e-mail to my client with small version of the image with a PNG-logo on top of it. Just like I can toggle watermarks on/off in Lightroom when I export.
It's also relevant when uploading pictures to various services.
You can already do that using File>Export...
Or did you mean something else?
