That's not always true: it depends on the filesize of the gif or jpeg.

Not all images scrunch down smaller, acceptably, to gifs. For example, if an
image changes colour a lot over a horizontal plane (simple example: a
graphic with different coloured vertical lines) a jpeg is (almost?) always
better than a gif, when trading off degradation with image size.

As always, it's horses for courses.

Liz, All I know is it worked for me. I first used jpgs for my
thumbnails and it took five minutes to load. When I changed them into
gifs they all load in a fraction of the time. I didn't see any loss. I
would never do a large image as a gif however.

Yes, that's correct.
And GIFs have two huge drawbacks:
(1) They are limited to a 256 colour palette, which is fine for line art
& business graphics, but nowhere near good enough for photos,
(2) GIFs use a patented compression algorithm, & the owners often
threaten website owners who use them without paying the license fee.

You've probably saved your JPEGs with too little compression, & ended up
with huge files. Try it with a compression/quality setting of about 3/4
of the scale & you'll probbaly see a great improvement. You'll have
gotten it right when your JPEG thumbnails are only a little larger in
file size (10-15KB) than the GIFs you're using at present. Photoshop's
'save to web' tool makes it really easy to optimise compression vs image
quality vs download time.

That's what I do. I reduce a jpg to thumbnail size and "save to web" in
PS.
I must have not explained my steps correctly. Sorry.

It works better if you start with your original image, select 'save to
web', *then* reduce size to thumbnail.
