Inserting an image in your post is easy.
You simply use the Attach functionality to upload your image:

And place the
[attachimg=#] tag where you want it to appear, the forum parser will substitute this tag for your attached image.
That's it!
You can get the tag by using the "
Link Inline Image.." Drop-down menu:

And selecting "Inline fullsize attachment":

Also, you should know when uploading multiple images your images will take numbers in the exact order you attach them:

You can use the
[attachimg=#] repeatedly to have them displayed in the order you uploaded them OR you can directly reference by their number/place, like this:
[attachimg=#1][attachimg=#2][attachimg=#3]As you can see the tag is flexible.
Hope this helps you to attach images to your posts.
Any doubts about this, just reply!
