Clients often ask me about sourcing photographs for presentations. To be safe (and compliant with most company copyright policies) I recommend using a stock photography company to source licensed royalty-free images. Skip the clip art and head straight for the good quality photography. A picture is worth a thousand words after all. Make sure that you choose the right resolution for projection so that you don’t end up with grainy images. Here’s a sale on now at iStock if you want some new images to refresh your slides.
