If you are trying to make a post on this forum: thanks so much!
You might be struggling with posting inline images.
If you are take a look at this image.
inline-imgs.png
After you've attached an image to the post click on the blue arrow while editing your post to insert the image.
A little box comes up
inline-size.png
add size details (only required if your image is very wide) then click insert.
took so long to figure this out :P
but makes sense in retrospect.
Also worth noting that if you add an image inline it won't appear below as an attachment either.
