Using Images spruces up you blog posts. Period.
This has been said again and again, so I’m going to show you a little trick(read plugin) which I use to use images with my blog posts and save hosting disk space at the same time.
If you dont already know, it is more convenient to use an Image Host for uploading images, rather than upload it to your own server.
ImageShack and TinyPic are the most reliable ones, and the ones I use. But the problem is that everytime you want to upload an image, you need to go to their webiste, upload it, and use the link in your blog post.
Thats where the ImageShack Uploader plugin by Arne Brachhold can make things a lot more convenient.
You can download it by clicking here.
After downloading it, upload it to your wp-content/plugins directory and activate it.
After activating it, an ImageShack tab will appear next to the Upload tag at the bottom of
WP post editor. You can now upload files from your editor itself without opening a new browser tab/window.

You’ll get several optios after uploading the image:

You can upload multiple images and use them as and how you want to.
PS: You can also use the edit image toolbar button in WP to change the alt tag, adjust alignment, etc.
