How to import wordpress posts with images from one wordpress site to another?
Step 1: Prepare your export file on the old site
On your old website go to 'Tools Export' and export your posts only.
Step 2: Import your posts into the new site
On your new website go to 'Tools - Import' and import the posts you exported. The importer has an option to download and import file attachments, but this won't work if you're not migrating all content, so you can ignore this.
Step 3: Install and activate the Auto Upload Images plugin
It installs as any other plugin in the WordPress repository. Once activated the plugin adds a settings page under 'Settings - Auto Upload Images', but in my experience you can leave these to their defaults.
Step 4: Get the image from your old site into your new site
At the time of writing the plugin has no option to automatically go through your posts and bulk upload plus update all the images. Instead, it updates each post individually when you save it. If you have many posts this is a lot of work, but there is a little trick. You can go to your posts overview screen and bulk update your posts.
