imgsrc : free html tool

imgsrc takes a list of html files on the command line and processes them, automatically putting height= and width= tags into the source code where necessary by finding the referenced .gif or .jpg and calculating its size. It doesn't work in all cases (like nonexistant or internet-referenced images), but can speed up web development in many cases if used.
why width= and height=?
Web pages which include height and width information for all images load faster. The client web browser can display a page with empty spots for the images while the images download. If there is no information in the html, this can't be done until the images have started downloading and the browser can figure out what size they're going to be. Unfortunately, if you code html by hand it is tedious to manually fill in each image's size.
imgsrc.exe (68k) Executable.
DOS / 95 / 98
To support long filenames under 95/98, type:


at the DOS prompt before running the program. source code This should compile with any ANSI C++ compiler that has rudimentary support for unix file/stream features. It is known to work with DJGPP (DOS) and g++ (linux / x86).
Run imgsrc in the directory where your web documents reside. The paths to images should be relative to this directory (either in it, or specified with a relative path). If the html references images with absolute paths (like /images/dot.gif), use the -r option to specify the local directory which represents the server root.

Run it like this:

C:\WEB\> imgsrc index.html

It will run and modify index.html in place, instrumenting it with height= and width= information when possible. You can also give multiple files:

C:\WEB\RESUME\> imgsrc doc1.html doc2.html doc3.html

Which means that under a bash-like shell you can give wildcards:

% imgsrc *.html

Maybe in unix you have your web docs stored in /home/httpd/html and you specify some absolute paths to images. Run the same way, but add the -r option:

% imgsrc -r /home/httpd/html *.html

imgsrc is distributed under the GNU public license and is free software. This means you can use, distribute, and modify it however you like, as long as you always make the source code available. You can read the license at GNU's Website.
No warranty whatsoever.

This program expects image tags to be formatted like this:

<img src=../something.gif>

And while it will accept some variations, there is surely some legal html which it won't accept. To the best of my knowledge, it should just ignore these situations (not insert width= and height=), though this is not guaranteed. Keep backups.

possible improvements

If you like, consider making any of the following improvements. I'll be glad to post improvements to imgsrc on this page. Remember that derived programs must also be GPL (open-source!).

  • Support more valid html styles
  • Connect to the internet to retrieve <img src=> stuff.
  • Build as an Apache Module, to run on webservers and modify the source at serve time.
