    When you resize your pictures, even if you resize to a large
    height-by-width size, just change the DPI (dots per inch) to something like
    72.

    This will make a huge difference is file size while keeping the height and
    width the size you want.

    Also, use good compression. I think JP2 has the finest compression of all
    (versus JPG and GIF but I'll add the photo group who knows which
    compression is best for full-size photos on Craigslist).

    What are your photographs of? Do they have lots of colors and detail?

    Not necessarily. In all the editors I use, changing the DPI has
    absolutely no effect on file size. You have to change the absolute
    size of the image in pixels (or the jpeg compression) to change the
    file size. I suspect the editor you're using must tie PPI to pixel
    dimensions in some way.

    In a web image ad, if the display size of the image is unspecified in
    the formatting of the web page, e.g. the html code, then the size
    displayed will depend on the size of the image in pixels.

    The 4 small pictures is what you get when you use craigslist to host
    your photos. No matter what the original size is, their ad upload
    process converts them to the small size.

    If you want to use large pictures, you have to host them somewhere
    else... like photobucket or flickr. Then you have to use the html
    <img/> tag in your ad to point to where the image is hosted.

    Thanks, Steve,
    Your solution sounds reasonable. However, I have no idea what "html <img/>
    tag" means. Text I put in my ad? I have web hosting from Tierranet, so I
    can put my picture there, probably, and I know how to point to it.

    You may not realize it but you're bringing this discussion closer to an
    exchange I had some time ago in a.c.f. with Hummingbird.

    He and I discussed pixel dimensions and it was the first of many bizarre
    discussions I had with Hummingbird in which he seemed unprepared to
    understand conventional terminology. Later I saw it was one of his k00k
    tricks.

    In that discussion, Hummingbird's way of defining terms such as "pixel
    height" was so contrary to normal practise that I called the thread
    "Humpty with Alice" because Humpty had said this:

    "When I use a word it means just what I choose it to
    mean – neither more nor less" [Etc. See link.]

    http://en.wikipedia.org/wiki/Humpty_Dumpty#In_Through_the_Looking_Glass

    I don't know if anyone is still interested in reading that original
    Hummingbird and Franklin discussion but here's the thread in Google
    Groups:

    The <img> tag is html code that you put as text in your ad. Craigslist
    allows it. So you would do something like this:

    -----
    Here's a picture of my item:

    <img
    src="http://www.tierranet.com/url/link/to/my/reasonably/sized/picture.jpg"
    alt="text describing my item to display while the picture is loading"
    width="number of pixels wide" height="number of pixels high">
    ----

    And then when someone's browser displays your ad, the <img> tag gets
    replaced with the jpg picture at the link in the src part of the
    element. The width, height and alt are optional and don't need to be
    there. They just make things look nicer while the picture is loading.
