Step to Step Guide to Post Pictures:
#1: Simply get a picture
You can use things like paint to take the picture by using the "Print Screen" button.
Tip: You can only take one picture at a time as they are removed after a new
#2: Save
Once you have gotten your picture save it for a base. You always want the original in case of mistakes made latter on.
#3: Modify
This isn't mandatory. If you want you could simply make it yours by editing it.
#4: Find an image hosting website
I recommend using imgur where you can simply upload without a profile.
Know: There are other image hosting sights.
#5: Upload & Show
After uploading your picture copy the URL in the search bar. Then go into your post and paste. If you want it visible without clicking the link simply highlight the link and click "Img" above.
