Is there an option to remove images from a project under a PPI Licence? If I added the wrong images or am not getting some images to align, or I need to get the cost down, it would be great to be able to delete them.
That would not be possible Sir.
What you can do is select the photos you like, export the image selection and import it back into a new project to isolate the ones you like. Also exporting and importing the component is a bit of a solution.
Deleting unused photos is not possible, so plan to delete them after alignment, starting a new project. Not that easy. If the calculation is already finished, you can reduce the size of the unused photos (1%) to avoid paying too much !
