OFPEC is not a general OFP site. It specialises in Editing related topics.
If they are pics from missions, scripts, functions, tutorials, tools or addons you have under devopment, that would be advertising which is not allowed in the OFPEC forums. (It is perfectly acceptable to post pics along with the resource.) If the pics are not from things you have under development, then it's hard to see how they can be related to editing.
So how does this relate to editing?
