If you use Instagram to market your products and services, I noticed you can now upload images from your desktop computer and not just your phone. I have to admit, they might have had this feature for much longer, but I only noticed it the other day poking around. This means you can take product photos and promotional images and easily put them on Instagram. Have a nicely designed flyer you want on Instagram? Grab it from your computer and upload it. There were ways around this with only using your smartphone, but now it is much much easier.
