* Picture File Size will vary depending upon the picture, the camera and camera settings used along with other possible variables.

Generally, using a JPG (or JPEG) format results in the smallest files size. The JPG Quality can also be varied using some image editing programs.
JPG files have a WHITE -background - if put over a colored, textured or picture background, the JPG will appear as a white rectangle over the background;
If a 'floating' picture is wanted (where the background appears all around the image with no white rectangle - also known as a transparent background)
then either a GIF or PNG format is required.
GIF and PNG File Formats have an Alpha Channel, which allows for the 'transparent' background effect.
GIF is an older format and is generally not recommended exept for some animated images.
PNG files are generally the best choice when a floating, or transparent background is desired.

In EITHER case, the background will have to be converted to transparent using a program or editor, such as IrfanView, PhotoShop or other suitable software.
