With a Canon PowerShot SD630 Digital Elph camera...?

...Is there any way to delete every picture @ once, or do you have to delete them individually?

Yes you can delete all images at once. (But make sure first, because once deleted, they can not be recovered).

In playback mode..press the MENU button, then scroll down till you get to...ERASE ALL IMAGES...press the FUNC. SET button to OK it.

Or look in the manual under ' Erasing All Images'.

Go to main menu and click to the erase submenu.
