I use an iPhone and a MacBook to post here, and lately I've noticed that I can't resize images either with an aftermarket app (iPhone) or with "Photos" and have it not fill the screen. In the past I could. Has something changed in Mac land? I like to be able to post smaller images for less dramatic effect sometimes. Thanks to any graphics wizards for help on this.
On your Mac, open the pic in Preview, select Markup (the little suitcase), and then the re-size box (square with diagonal arrows). Pick from various sizes to get the one you want. Viola!
^ Jim you have a big future in front of you in tech support. It might shorten your life by about 10 years though so factor that in.
For most of my office bound life I was the "go to guy" for IT support, even though I still had my real work to do. I'm glad it's no longer the case! Don't mind doing the occasional tip for others though .
