passing parameters to .html, parameters html Options

[koffeeman]

i feel 'comfortable' with .html but i do not consider myself 'expert'
- i would like to ask for help on something i am trying to do:

to simplify:
i generate many (MANY) .html files whose sole purpose is to display .jpg files and (optional) descriptions. currently the high level .html has 3 links:

<a href="grid3.html">3-Across Grid</a><br>
<a href="grid6.html">6-Across Grid</a><br>
<a href="grid9.html">9-Across Grid</a><br>

to which i call the appropriate subsequent .html where the only difference is in the "width=" parm on the

<img src="xxx.jpg" width="33%" alt="a01"> [in grid3.html]
or
<img src="xxx.jpg" width="16%" alt="a01"> [in grid6.html]
or
<img src="xxx.jpg" width="11%" alt="a01"> [in grid9.html]
tag.

this provides a grid of the .jpg file either 3, 6 or 9 across - the three gridX.html files will display the same .jpg list of files.

i would like to just call ONE grid.html file from the high level .html file, passing the subsequent grid.html file a single value (the percentage: 33, 16, 11)

this will mean
a) that i only need to generate ONE file, and
b) i can add single, 2-across, 4-across, 5-across, 7-across, etc. "any-across"

when i go to .html help sites for 'passing parameters to .html files' i get much more complex answers using "gridX.html/? pctg=xx" and requiring javascript to 'get' the parm and never a description/example on how to use the parameter when i have it, into the <img tag's 'width='.

IS THERE ANY SIMPLE WAY OF SPECIFYING A WIDTH in an .html
AND PROVIDE / USE, THE WIDTH, in a subsequent .html
?

to admin's: if i have posted incorrectly, i'm sorry, and please feel free to delete this question.

Or, if the OP's goal is just to let users change the size of images on screen, it can be done much easier with the browser's own Zoom control --at least if there's no text on the page that would get zoomed too.
