I have a table with some images that I want to start out with no images in them.I have set the src=\"\".But when viewed in a browser it shows broken image pics.
Don't use images that point to nothing.
You could style them to have no visibility (will not work if you have anything in the src attribute, even if it is a bad URL):
src
img[src=''] { display: none; }
But as I already said, if you don't have an image do display, don't put the tag on the page.
