Hello Everyone hope somebody can help!!

I have recently purchased a wordpress template and hosting through 123-reg, I have uploaded the data to the hosting platform. I then went to my web page and followed the instructions and can know get into the wordpress dashboard. I then uploaded the template from gavick but it has come with no demo data. When I click to view website its looking nothing like how the template did all images etc are missing. I was hoping this was going to be simple can anybody help?

You need to download quickstart package and install wordpress manually (which means not with use of hosting company 1 click WP install).
Here is a brief documentation on the process, but it might be a little different for your hosting comapany:

If you don't know where to put the files, or how to create the database - please ask your hosting company support for help.

I know have this working and have the demo data up but I am unable to change the pictures on the site they let me upload but not change does anybody know why?

Could you confirm, that after uploading new image with use of WordPress media upload module - you can see it in Media Library?
