Ok, so my site is centric to a lot of dynamic user entered images for different user defined objects throughout. So I have many objects, and those objects have images. Is it good practice to treat images like an object since the "Image Name" and "Image Bytes" columns are repeated many times? Or is it more sensible just to include those...

In javascript to create an object, var student = new Student( 33 ); document.write( student.age ); function Student( age ){ this.age = age; } In a...
