Your links need username and password. Please put them somewhere that doesn't need username and password.
It might also help is you say what version of IM and platform you are using.

Thank you for pointing out the permissions issue. The images are now accessible.
I use ImageMagick-6.8.7-8-Q16-x64-dll.exe (Win64 dynamic at 16 bits-per-pixel)

Your tif is CMYK and many browsers do not display CMYK jpeg properly. So convert the tiff to sRGB using profiles and that works for me in IM 6.8.7.8 Q16 Mac OSX
convert image.tif -profile /Users/fred/images/Profiles/USWebCoatedSWOP.icc -profile /Users/fred/images/Profiles/sRGB.icc -thumbnail 150x250 image.jpg

You have to use your own path to your profiles, not mine. Find or download icc or icm profiles of the same names to your system and put the full path to them in your command.
