<< So the thing to copy in is the HTML.Code given after upload of png to imagebox.

Yes with some possibilities...GIF PNG JPG:10 meg max each
And you can just copy a part of the html with balise "image /image" so have directly the original size!
Moi's Forum resize it automatically if necessary!

The cool thing of Imagebox is that you can make some Galleries named for your own use!
And all is free since more 7 years!
