LyX on my system (Mint) does not have a converter defined for GIFs, 
maybe because the GIF format is so 20th century? :-)  At any rate, I'm 
pretty sure ImageMagick can convert GIF to JPG or PNG or maybe EPS. I 
suggest try to convert one of the files using ImageMagick, and if it 
works, just define a GIF converter using ImageMagick in LyX.
