Yes, I have seen this quite often. I'm still amazed how many people will, when asked for a copy of their company/product logo for print production (preferrably vector), I'll receive a crappy Jpeg from their website. Unless you have a 72 dpi file and a 300 dpi file of the same image to compare, there's really no way to tell if the image has been resampled. And even if you do have 2 files to compare, there's no way of telling if the 300 dpi file was resampled up from the 72 dpi file or the 72 dpi file was resampled down from the 300 dpi file. The best you could do would be to compare the pixel dimensions (if they are the same, then the files weren't resampled)
