When you are writing your post, open a folder on your computer. Drag the picture you want to display on your post and drop it on the text.
A line will appear looking like that !(name-of-your-picture)...
If your picture isn't where you want it to be, cut the text defining your picture and paste it where you want it to appear.
I hope It's clear.
thank you so much. ill try it now :)
Did it work?
