This by no means a fool-proof method.
First look at the pics - not just their bits!!!! Look for:
Jewellery - rings, chains bracelets, watches, are they still there in all pics? Is it the same jewellery?
Tatoos - Have they disappeared/appeared?
Background - 2/3 rooms, look at the decor does it match? i.e. wall colour and paper, has it changed?
Patterns - bed-sheets, duvet, carpet, furniture, do they match? i.e. same headboard?
Style - the same styling normally(?) runs throughout the house, is one pic clean and tidy, the other pic tatty?
Bodyshape (very difficult) - look for any irregularities i.e. disguised faces, head shape has it changed?
Agree with Sexysteph a cam is probably the most effective answer!!!
This is the criteria we use when selecting from photo-ads and we have still been caught out. Like the rest of us you have to grin and bear it unfortunately, its a mad, bad world out there!!!!!!!!!!!!!!!! Hope this helps anyway.
