Likely many of you
will want to use these images either as hard copy or on a personal or
an office Web page. All of these images are in the "gif" or "jpg"
format. If you wish to convert these images into a format that you can
use in the office as hard copy, say for use in a Word document, you may
need a software conversion utility.
Irfanview
is an excellent freeware imaging program which converts to and from
most major formats.
These images are bitmaps where each pixel is
assigned a value. You might have trouble resizing them while retaining
image quality. If you need to resize the image check your imaging
software. The best have an option called resampling.
This attempts to preserve image quality during the resizing process.
Should you want to use an image on a web page there is no need to
convert image formats but you may want to create a transparent
image that floats over the background. GIF's were the only way to do this in the early days but now the PNG format is superior. It supports more colors and partial transparencies.
