This is because continually saving a compressed image reduces its quality each
time. Also, under no circumstances should you increase the dimensions of a compressed
JPEG. Doing so leads to abysmal results every time.
Overwriting original documents
The previous problem gets worse if you??™ve deleted your originals. Therefore, be sure that
you never overwrite the original files you??™re using. If resampling JPEGs from a digital camera
for the Web, work with copies so you don??™t accidentally overwrite your only copy of
that great photo you??™ve taken with a much smaller, heavily compressed version. More
important, if you??™re using an application that enables layers, save copies of the layered
documents prior to flattening them for export??”otherwise you??™ll regret it when having to
make that all-important change and having to start from scratch.

Communications homepage. However, if backgrounds are too busy, in terms of complicated
artwork and color, they??™ll distract from the page??™s content. If placed under text, they
may even make your site??™s text-based content impossible to read. With that in mind, keep
any backgrounds behind content subtle??”near-transparent single-color watermarks tend
to work best.
