Image Error Level Analyser - Could Be Useful

Guys,
I have come across this useful tool which analyses JPEG photos to see if there has been any significant enhancements made to it.
Take a look at this website and read the part under 'Example' to get an idea of what to look for.

Now if we are unsure of whether or not a JPEG photo has been Photoshopped, we can use this to give us a better idea. I wouldn't rely on it 100% but surely it's better than using the naked eye and judgement and besides, it's also quite fun to use.
Error level analysis is a quick and easy image forensics method, allowing one to determine if an image has been modified by programs such as Adobe Photoshop.
It works by resaving an image at a known quality, and comparing that to the original image. As a jpeg image is resaved over and over again, its image quality decreases. When we resave an image and compare it to the original, we can guess just how many times the image has been resaved. If an image has not been manipulated, all parts of the image should have been saved an equal amount of times. If parts of the image are from different source files, they may have been saved a number of different times, and thus they will stand out as a different colour in the ELA test.
It is worth noting that edges and areas red in colour are often depicted as brighter in the ELA tests. This due to the way the photos are saved by various programs. It is not proof that image was manipulated.
If you are unsure how to interpret the results, please do not claim the results of this tool as proof of anything.

Seems like a genuine picture to me BUT we have to remember that SDG is a photographer so she could know how to manipulate this sort of thing so that it can't be analysed and give a true result.
See the lighter areas where the woman is? This indicates that that part of the image has been saved more times than the rest of the picture and therefore the pic has potentially been Photoshopped.
Gosh I could use this tool for hours! What fun!!
When were those pics taken? Is that the "real" MJ?
From what I remember reading a while ago I think they were taken during TII rehearsals. Yes, it would appear that the SDG pic and the one of the brown haired lady are genuine, but the others are very questionable.
It 'appears' to be real yes.
SDG is very active promoting Sony as a murderer. Having a pic with Mike only proves that she sat with him in that car, but not further or previous relationship with him.
If the pic is real it doesn't prove anything about the hoax at all, which I think is what you are saying Gema. Merely that yes, she was sat in the car with him and had her pic taken with him 'at some point' but for all we know, it may not have been during the TII rehearsals, could have been way before then. And of course, it doesn't prove anything about any sort of close relationship with him either <!-- s:) -->:)<!-- s:) -->
scratches head and mutters "why oh why can't we all just get on?"
Doesn't prove anything in regard to Michael's hoax, but it does shed some light on if the pic itself is a hoax.
I have used the analyser on both the ambulance pic that alleges to show Michael AND also the other one that was floating around which didn't clearly show the face of the person on the trolley.
I'm not sure what to make of this BUT it's clear that the second one has been tampered with a lot - odd as I would have thought that the first one would have shown more evidence of tampering:
What do you guys think?
resolution: 442 x 639 px
resolution: 480 x 321 px
To me it´s odd that The photographer, a.k.a Michael´s friend would have been at the right place at the right time and catching that ambulance pic so nicely.
The ambulance pic may be is real, but from a another year or time, even can be a set up, a stage.
I doubt that pic was taken on June 25th.
