Hi Guillaume,

you have a button called "external link" below the text field. There you can attach different files such as images or bits of code and so on. Find out more through the "Help" button.
Regarding the video, I don't know. Try using the external link button.
You can check the result before posting by clicking the "Create & Preview" button.

Also, you forgot to attach the actual script so there is no way of downloading it.
I look forward to try your script out. It is always fun to see what helpful scripts users of Scriptographer come up with.

Thanks!

Okay so since the cms will try to show any tag I put in here, I will use an image instead:

Thanks for the quick answer.
and happy to share.
i still have a problem, strange i can post an image in this post for exemple with the tag. But i'ts not working for my script post.
i tried many times with all the differnent tag. External stuffs work (such as video) but not internal.
are not working. it seem to be a problem with my uploads.
I finaly tried to delete my post to create a new one. But it wasn't possible to delete it.
is there an alternative?

I did a new post & it work.
Can you delete the old one.
Thanks.
