All images ought to be optimized and re-sized prior to uploading them into your blog. When you decrease the file size for images before you insert them into your blog, uploads and pages will load faster, you can fit more images into the same space, and using the correct tools means you will not compromise the quality of the image.
I have previously reviewed and blogged about several free image optimization and resizing programs bloggers can download and use locally. This post is aimed at the programs that are available to us online.
The image I use above is an example: Original Image 962 x 762 -179 KB
Types of Images
- JPG works best for images with gradients such as photographs.
- GIF are best for blocks of repetitive color including logos, line art, and illustrations with type.
- PNG should be used to preserve partial transparency and a large amount of colors. PNG images often take up more space, so try the GIF format first to see if it works well for your image. From: Media Library » Image Optimization
