Some times your download images have odd names that don't make sense. If you are uploading an image having a alpha-numeric name rather than useful text, than even if you add alt and title tag to it, you are hanging your blog's ranking. Didn't understand? Let me share.
Optimize Your Blog Images Before Uploading

Tips For An Optimized Image Ending Point
- Try to use short names for your image. 3-4 letters are best for your image name.
- Use only best keyword and do not use connecting words like "are, with, for, yet, so, also, if etc".
- Do not tag images with useless words. If the image related to an installation process step for example WordPress self hosted blog. Then instead of writing as "Cpanel Settings" or "Next Step" rename it with a rich keyword like "wordpress installation" or "wp-self-hosted-blog"
- Avoid use of special characters like !, *, ~, @,`, ^, / etc.
