resizeMove() - resizes the picture to $maxMedium and $maxSmall and moves the file to a permanent location.
makeDimensions() - calculates the dimensions of the new images so that there is not distortion if possible.
getImage() - creates a php image for manipulation.
updateSessionAndDb - updates the mysql table - move out.
