Sure.
You can enlarge any image file to poster size. A jpeg (being 72dpi) will look like cr*p once it's that big but, sure, you can do it.
I wouldn't, though.

BMP, JPG, GIF... are all designed for web viewing and typicaly are about 75 DPI (bad for printing).
Your ideal image should be 250-300 DPI (minimum 150)
Then your image should be saved as a TIFF, EPS, or PDF.

Anything you pull off the web as a jpeg/gif/bmp etc will look like crap when printed, especially if you enlarge it to poster size.
If you want to use an image probably the best thing to do is find one from a magazine and scan it at 300 dpi.

I am a print designer and of course always use art at 300 dpi for print----
HOWEVER....
When we make posters and signs, our Large format printer (outsource company) requires 100 dpi at 100%. So a poster at 18x24 - I either set up as 6x8 at 300 dpi or 18x24 at 100 dpi. Now, normally I would not reccommend this but I have found that the printers our sign people have are different dpi and have a different interpolation formula than that of offset printing.
The final product is beautiful (depending on the material) at 1 foot away as it is 10 feet away.
As for JPG- it's not the format- it's the compression that kills you. NONE or MINIMAL is best- what difference is that if your file is created (not resampled) at a nice resolution to begin with? 300 dpi JPG are fine- but not the old school 72 dpi at 1"x1"...
