Hello ShakuZen,
there are three ways to place an image or other media into a Pages document.
1) If it is one of Pages own templates and you want to exchange an image, just drag and drop your image from the Finder window over the image in the template, because all images in Pages own templates are placeholders and they are defined for this task.
2) You can drag and drop images out of some apps like Safari, iPhoto and of course from Finder windows and others into a Pages document.
3) You can use the menu item "Insert/Choose..." to import images or PDFs etc.
But there is one thing you have to know: if the text cursor is visible somewhere on the page and you are using the "Choose..." function, the image is automatically placed at the cursor position and it is an inline object. So make sure the text cursor is not visible (by clicking outside of all text areas near the page border), if you want a fix positioned image. Of course you can change the positioning mode every time with the wrap inspector.
