Graphics (Characteristics 1)
Images have various characteristics that
affect performance
Size (number of pixels) – Large images can be several megabytes Color (bits per pixel) – The more colors, the larger the image Compression – Algorithms exist to compress images without any loss of fidelity
Graphics (Characteristics 2)
Interlacing – loads and renders alternating
lines to improve perceived performance
Image Maps (Creating)
Use the element
