Tom,

Images are not that simplistic. GIFs have smaller file sizes when the number of colours is restricted, such as text, line drawings and shapes with big areas of uniform colour. JPGs have smaller file sizes for images such as photographs. JPEG stands for Joint Photographic Experts Group.

A photograph saved in GIF form can look good, but it really will have a bigger file size than the same photograph saved in low-resolution JPG form.

The quality of resolution (High, Medium, Low) has significant influence on the file size of a JPG, as well as the physical size in pixels.

Hello,

To really reduce the size of photos save them into the GIF format. This can be done simply with the Microsoft Paint program found in the Accessories. Colors may change slightly, but usually not significantly.

Most of the time these minor color changes do not affect NAFEX usage, which is simply a reference image.

A JPG file has millions of colors, where a GIF has thousands of colors. The more colors, the larger the file becomes.



Later,

Tom
