"Image" stuffs i would like to do, but i need your help

[Goodman_2020]

Hrllo,

Im' trying to do something but i can't suceed so i need your help (im a noob sometims )

1.When you insert more than one image coming from an imagehost on the web (not as an attached file, but as an image inside the text you know) they go in a column.
Me i would like to have horizontally... but i don't know if it's a code to insert, which one it is, or if a hack can do that.

2.Second thing, when i insert only on image (still from an image host), i would like to center it but i don't know how to do it (i tried <center></center> but it doesn't do anything. Is there a hack or a code to do that?

3.By default on vbulletin you can't insert an image directly from your comp?ter (you can do it only as an attached file), al lyou can do is add an URL where your image is, or use web image hosting and then paste the link of your image. Is there a hack that allow to insert images directly from our computer?

Thank you!

I use 3.6.9 but will probably go for 3.7.0
