Where can I host big images and videos?
Because you’re paying a very low price per blog, we really cannot afford for you to host big (or a lot of) image or video files.
For video, the obvious solutions are YouTube or Vimeo. With images, you should look into Flickr, Photobucket, Imageshack, imgur, PostImage, TinyPic, and UltraIMG.
You can also use a CDN service for images which will automatically move your images to their servers and correct the links on the blog. See this blog post for more information.
