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
