Posting images on topics

Hello I was just wondering how I would go about posting images on my topics. 
I am working on my first tag recolor sale and was trying to make an interest check post but can't figure out how to add images (the insert image option did not work for me) 

Some help would be appreciated! Thank you for your time 

You have to upload the image to a hosting site like imgur (making sure it ends in .png), then right click the image, and select 'copy image address', and then paste that into the 'insert an image'. If you just copy the url in the url bar and then try and use the insert image option, it won't work.

Ah ok that makes more sense lol. Thank you!
