Blog section for PR needs adding to our site

We have just setup a new company which we would like to add a blog / news section too. [login to view URL] The above link will take you to our website. The website runs on the ecommerce system cubecart, a knowledge of this system may be good as we would like to incorporate the blog / news section as much as possible. Features of the news PR page must be: 1) The ability to upload text and images easily. Preferably when multiple images are added, it creates a gallery a bit like the one on this site -? <[login to view URL]> (doesn't need to have as many boxes as it would be a maximum of probably 6 images being uploaded). 2) Some kind of archiving, so that when a new press release or news section is added, old ones are filed and can be viewed by people. 3) The ability to add / change text at the top of the news / pr / blog page. 4) The blog section must be within our current website, it cannot be put onto another website or look different. Something like this would be fantastic (obviously themed to our website though). <[login to view URL]> I believe that is using wordpress and possibly feedburner? We are open to suggestions but would like to keep costs to a minimum. Any scripts that are used need to be SEO friendly ! :) Kind Regards Lewis
