I know this is not the type of Instructables I usually post, but I need to mix it up. If you didn't know how to post pictures in the comments of Instructables, now you can know!
Step 1: Find an Instructables
Find an Instructables you want to post a picture in the comments on (preferably mine). And press on the button that says "Comments".
Step 2: Magic
In the comments, press on the icon of a camera. It will say "Choose Photo" or "Take Photo".
Step 3: Done!
You can post anything now! Well maybe not anything... Anyways, enjoy and post pictures!
