Creating images to post on Instagram from my computer

I love to put text and images together to make inspirational images and post them on Facebook. Recently, to try out another social media venue, I created an Instagram account. The problem is that I don't upload photos from my phone and that's what Instagram is designed for. Fortunately, I found a freeware program called Inxtify that works on my Mac. I'm able to create images in Photoshop, drag them to the Inxtify loader window, and either publish immediately or schedule. Here's the Instagram post that is scheduled for tomorrow. I'll need to have my computer on at the time I've scheduled for this to work. The program is easy-to-use and does just what I need it to do.
