Should you place all the images images in a Word document? Would it be better if they were placed in individual PowerPoint Slides?
Well, actually, the very best way to share images is just to share the original file. That way, the image keeps the resolution it started off with—and your designer can choose to crop, resize and generally mess with it to their heart’s content. The problem with placing it into another program, is that the programs downsample the images i.e. lower their quality.
OK, but there are so many! I can’t just attach everything to an email, can I?
Unless you are sending only a couple, you should definitely avoid adding all of them to your email. Doing so might clog your outbox, crash your inbox, or cause the message to take permanent residence in your outbox—never leaving. It might also leave fine, and instead mess with your designer’s inbox. I recommend: either uploading the images you want to share to a google drive and then sharing the link to the drive; or zipping/compressing it and then using a free mailing system such as wetransfer.com. Easy-peasy.
