Why including picture to your post

Including images in a blog post is a good way of capturing your readers’ attention and making the post more interesting. Some people connect better to visual formats than written ones, so by including both images and text you’ll be appealing to a wider base of readers.
Uploading images to posts is easy and intuitive on most blogging tools: when you’re creating a post, simply navigate to where the image is stored on your computer and upload it into the body of the post. When you upload an image, you’ll be given various options for the size the image is uploaded as, such as thumbnail, medium, or large. You’ll also be able to add a caption, description, and URL to the image if you want it to link to another site or post on your blog. If you want to include an image on your blog that you don’t own, be aware of copyright issues: credit the image source by linking back to the site where the image originally appeared or e-mail the owner directly for permission to use it. Another option is to purchase the rights to an image through stock photography sites like www.istockphoto.com and www.gettyimages.com.
If you don’t want to store your images on your own hard drive, you can store them on an external image-hosting site. Doing so saves space on your own computer and gives you a centralized image storage location – particularly useful if you have multiple contributors to the same blog. Examples of popular free image-hosting sites include:
Flickr: A free account allows you to upload two videos of 150 MB each and 100 MB’s worth of photos per month. Image size is limited to 10 MB each
Picasa: A free account gives you a maximum of 1 GB of storage space for images and videos. Image sizes are limited to 20 MB each, and videos are limited to 1 GB each if uploaded from Picasa.
TinyPic: Unlimited storage space and bandwidth, but images are limited to 1,600 pixels in either length or height, and videos are limited to 100 MB and five minutes or less in length
ImageShack: Unlimited storage space and bandwidth, but images are limited to 5 MB in size, and videos are limited to 15 minutes for free accounts.
Photobucket: A free account gives you 500 MB of storage space and up to 10 GB of bandwidth per month. Image size is unlimited for images up to 1024 x 768 pixels, and videos can be 300 MB or less and must be 10 minutes or less in length.
