Optimizing to be bandwidth friendly
The key to optimizing web graphics is to minimize their size, number, and quality, and maximize cropping. Combine adjacent images and use client-side imagemaps instead. Substitute CSS-based rollovers for bandwidth-hungry image-based rollovers. Replace graphic text with styled text. Finally, to minimize HTTP requests, reuse images with the same URL. With all graphics, you can't go wrong if you do the following:
* Eliminate and combine your images to minimize HTTP requests.
* Convert graphic text into styled text.
* Maximize cropping and minimize dimensions.
* Use the right image format (JPEGs for photographs).
* Use interlacing with care (avoid interlacing on smaller images and most PNGs).
* When capturing photographs, use a stable platform, (tripod, image stabilization, or a Gyroscopic stabilizer)
* Minimize noise, smear, and complexity.
* Use weighted optimization to reduce less important areas and blur backgrounds (for JPEGs).
* Minimize colors (bit-depth) for palette-based formats.
* Use a high-quality quantizer on true-color originals and limit dithering.
* Set your image resolution to 72dpi.
* Specify the actual height and width of all images.
* Use grayscale whenever possible.
* Experiment with different settings and programs.
Optimizing to be search engine friendly
Search engines just love rich content however it is blind when it comes to images. There is a cure for this glitch just make your graphics / images more friendly, spider friendly.
* Add alt tags in your images and use your keywords
* You can use your images for links
* Around your images, describe what the images purports and don't forget your keywords
