Dummy_renamed page already on site


I have just renamed a page already on the site.

Now will try and upload an image from my hard drive .. unsure how to follow instruction to resize image before upload in RGB format.  I wonder how to get text to flow round the image - even despite the setting of pic being flow round, align left.

When looking at live page - I see the banner at top, presume this runs through all pAGES ?

Also I see 2 pix on RHS that seem not to be on the page when I edit ?
