Those techy, geeks in the audience that use an iPhone probably recognize that the photos they take are in a format that's generally a little... Tricky to use with other resources. Seems I most frequently run into this issue when working on updating my blog with pictures that I took on my phone. I really would much rather use a .png format in place of the somewhat irksome .heic format that my iPhone captures. There's plenty of things online that I could upload my photos too, but who really wants to do that? I'd rather use something a little more "close to home."
