When I download a gif from my website script, it appears like a thin line. I expected to see the 1" by 1" graphic solid color image that appeared on the site. Is it just a thin line that expands once the web page size is set? How does this work?

Short answer for : the GIF you saved is almost certainly a tiny tile (often 1×1 pixel) that the site uses as a repeating background. On the page the browser repeats that single pixel many times so it looks like a solid square; opened by itself it’s still just one pixel (or a 1px-high line if your viewer stretches it).

Practical examples (original and simple):

/* repeat a small tile across the page */
body {
  background-image: url('tile.gif');
  background-repeat: repeat;
}

/* use a single image stretched to cover the viewport */
body {
  background-image: url('big-background.jpg');
  background-repeat: no-repeat;
  background-size: cover;
}

If you want the image shown inline instead of tiled, use an IMG element with explicit dimensions (these affect rendering only — they don’t change the file itself):

<img src="solid-square.gif" width="96" height="96" alt="solid color square" />

Troubleshooting checklist:

  • Inspect the saved file’s pixel dimensions (image editor or right-click → Open image in new tab). If it says 1×1, it’s a tile.
  • Use the browser DevTools (Inspect element → computed styles) to see whether CSS is repeating or scaling that image on the site.
  • Remember: web layout uses pixels. CSS units like 1in map to CSS pixels (usually 96px) and won’t guarantee a physical inch on every screen.
  • If you need a downloadable square of a specific size, create/export one at the required pixel dimensions (e.g., 96×96 px for a nominal 1" at 96dpi) or save a screenshot of the rendered area.

As noted, small tiles save bandwidth; and as warned, if you use <img> keep the markup valid and include alt, correct attributes, and proper closing.

when an image is used as a background, it can be,
repeat-x repeat-y or repeat-both
to tile the image in the direction of its repeat
a tiny image afew bytes in size,
two squares, become a checkerboard
a few leaves repeats to a forest
instead of a very large graphic to be downloaded
then the image looks 'right' at most resolutions and window sizes

true it is used to set length of website

You can edit the background image with a repeated x and repeated y by editing the codes of the background.

You need to add the height and width to the code. Here is an example. It is in pixels not inches.

<html>
<body>
<img src=""188" width="303"

what's wrong with the answer?

You've revived a thread that has been dead for five years. You might want to familiarize yourself with Daniweb's rules.

Apart from that your example contains errors. The image height attribute has become part of the querystring because of some missing characters. And the IMG tag isn't closed properly.

In fact it won't validate as HTML. IMG tags should have an alt attribute these days, and a minimal HTML file needs a HEAD and TITLE tag.

That said, it's usually best to keep code examples as short as possible. You could have discarded the HTML and BODY tags altogether, and the lengthy querystring is unnecessary.

Don't use any old domain name in your URLs. Prefer example.com or one of the other TLD domain names set aside for this purpose. Linking to real domains can have unexpected effects, and you can't guarantee what that link might point to in say five years time.
