The LoadPicture function does exactly what it says so that part is quite 
easy.

Zooming is more interesting as selecting which portion to view could be 
tricky, the actual enlargement can be done with the StretchBlt API or by 
using a Image control instead of a PictureBox as it has a Stretch property.

The easiest way I can think of would be to place an Image of 4 times the 
size of the picture inside a PictureBox then load the picture to the Image 
control and you now have a magnified view of 1/16th of the image and you can 
then work out what method you want to use to move the viewport around. Not 
all that elegant but it should work.

These suggestions relate to VB6, if you are using a later version of VB then 
it will probably require a slightly different approach.
