If you already have an existing blog you can very easily import your existing posts images and all other content into your new blog on theimagefile. This will mean that your existing search engine optimisation and log history will continue to service your new blog.
The first stage is to export your existing blog posts and content to a file on your computer. Login to your existing blog site and export the.XML file containing all data. If your existing blog is a WordPress site you can do this by going to Tools -> Export. More information is available on exporting from other blog providers by visiting http://en.support.wordpress.com/import/.
To import as it was to export. On theimagefile site login to your WordPress blog and on the dashboard go to tools -> import. On this page you will have a browse/choose file button. Select the XML file you exported to your desktop, and import it to your WordPress blog.
Your WordPress blog will now contain all existing posts of your previous blog.
