Please take a samnple of poop immediately for a fecal exam. Animals that thin out that quickly more often than not have a parasitic infestation. If she tests positive, you'll have to treat everyone else in the tank. Next time, isolate your new leo until a fecal proves it is clean of parasites.
Put her on paper towels, collect the poop and bring along a piece of the paper towel. Although mites aren't internal parasites, they can show up in fecals, because they live in the vent, ears, eyes, etc.
If she has pinworms, mites, or what have you, you'll worry about fattening her up later on. Waxies are good, but my fatties really blow up on gutloaded crickets. They're porkers though!
The pic is kind of blurry, I don't have my contact lenses on, but I thought I saw a little smear of orange in the base of the tail. I don't know... I've seen sellers calling something with that much orange a carrot tail or tangerine. Some give percentage of coloring too... Look up pictures in the Net and see if she looks similar to any of those.

Yes, you can revive lizards with CPR, and crickets DO NOT transmit pinworms to lizards
