I'm hoping that one of the experts who sell PowerPoints could answer this for me please... When you make a PP to sell how can you secure photos or clip art that you have used in them? Do you secure them or do you just use clip art that you haven't paid for but are available for free commercial use? I would like to make some and have some lovely clip art to use but the terms and conditions when I bought them state that it needs to be secure so nobody can just simply 'lift' it off the slide. I know how to make a PDF and secure that. I did start thinking that maybe your PP slides just contain PDF on them. Sorry for the probably silly question but after all the issues with copyright that are going on around here I don't want people simply stealing stuff that I have paid for.
