Yes, adding some smoke or an extra missle may seem inconsequential and you could could chalk it up to 'regular' bias for the underdog by an overzealous local photographer.
The reality is that these are just glaring examples of media manipulation by those who have an interest in depicting Israel as a careless warmongering state.
"CNN senior international correspondent Nic Robertson admitted that his anti-Israel report from Beirut on July 18 about civilian casualties in Lebanon, was stage-managed from start to finish by Hizbullah. He revealed that his story was heavily influenced by Hizbullah's "press officer" and that Hizbullah have "very, very sophisticated and slick media operations."

Other manipulations being reported - constant filming of the same destroyed area, but labeling it a different neighbourhood each time, so as to make it look as though dozens of areas are now rubble when in fact it is only a few buildings; The same child on a streacher being carried past the same destroyed building by different streacher-bearers for different news agencies.
And yes, you could point out that these links are to pro-Israel sites that have their own motive for distributing these reports, but when a CBS reporter comments that "Hizbullah is also determined that outsiders will only see what it wants them to see." and a Time magazine reporter notes in his posting that "The Party of God has a copy of every journalist's passport, and they've already hassled a number of us and threatened one." clearly not just the pro-Israel sites are catching this.
Hard to report the truth when you are wondering what terrorists will do to you or your family later.
