Where is my created preset that i make (unlisted) because in my profil it's not shown..

Not sure how but you made it "hidden" I just found it in the database and re-checked it as "visible" and it's now back. :D For the future could you try to keep the screenshot amount down, it's just some friendly advice, there is no LIMIT on how many you can post but having more then 5-10 in my opinion isn't needed, especially if alot of them are very similar, it also saves on webstorage space :P

Okey Sorry for the number of screen ^^ i will make some other but in différent environnement for the size you can make a bulk smush.it for all your site ;)

By the way how can i delete some screenshot ? the only way is to edit them ?

just uncheck "Visible" in the screenshot edit option

There is not official "Delete" button for screenies or presets besides coming to me or Terrasque himself lol, sooooooooo if you need something, leave a message or send one to me on Steam: OmnipotusX :P
