Add an image
Once you've selected your image, you can then choose a layout to determine how your image will appear in your post:
• The 'Left', 'Center', and 'Right' options allow you to customize the way your blog text will flow around your image.
• The 'Image size' options will determine how large the image will appear within your post.
Click UPLOAD IMAGES to add your image, and then click DONE when the notification window appears telling you that 'Your image has been added.' Blogger will then return you to the post editor, where you'll see your image ready to be published to your blog.
You can also publish images to your blog using your mobile device, Google's free photo software Picasa, or a third-party service like flickr
Add a video
To add a video to your blog post, click the film strip icon in the post editor toolbar above where you compose your blog text. A window appears prompting you to 'Add a video to your blog post.'
Click Browse to select the video file from your computer that you'd like to upload. Note that Blogger accepts AVI, MPEG, QuickTime, Real and Windows Media files and that your video must be less than 100MB in size.
Before uploading your video, add a title in the 'Video Title' box and agree to the Terms and Conditions (you'll only have to do this the first time that you upload a video with Blogger). Then click UPLOAD VIDEO.
While your video uploads, you'll see a placeholder in the post editor showing where your video will appear. You'll also see a status message below the post editor letting you know that your upload is in progress. Depending on the size of your video, this usually takes about five minutes. When it is complete, your video will appear in the post editor.
