You can easily upload images to DropBox by using this App.
When the upload is completed, HTML code for displaying the image is generated.
The generated HTML code is a code linking to the image on DropBox with ＜IMG＞ tag and ＜A＞ tag.
You will be able to easily display images on DropBox on blogs and homepages.
So, I wish that will help you update your website.
