Is there a way to add up for example the total amount of images stored in a folder on your root drive
and then store that value in a variable ???

much like you do when we add up all of the images in a document

e.g.

CODE


document.image.length



that gives us the total amount of images on that page , right ?

or am i being stupid lol

I don't know if with JavaScript this is possible, but you could use PHP to read all the images in the directory and then store the name in an array and count how many items are in the array.

I don't know much about JavaScript but if can scan a directory and count how many of a certain file exists, then it would be possibly but as a limited scripting language, it may not be possible.

Javascript will only be able to brute force it, meaning that if you want to you could have it go through an infinite loop trying to find all possible filenames in a certain directory. This will cause problems in a browser, and may even cause it to crash.

What you will want to do is use something like PHP or ASP to get all the images from a directory and output them into the javascript so it can calculate the number of images and use them.

I am no master of ASP, but a quick google search did pop this up:

CODE
<%@ Language=VBScript %>
<%
option explicit

dim fs, root

set fs = createObject("scripting.filesystemobject")
set root = fs.getFolder("c:\program files")
showDiskspace fs, root
set fs = nothing

sub showDiskspace(fs, folder)

dim s

if folder.subFolders.count = 0 then
s = folder & " [" & folder.size & " kb]"
display s
exit sub
end if

dim subFolder

for each subFolder in folder.subFolders
showDiskspace fs, subFolder
next

end sub

sub display(s)

Response.Write s & "<br>"

end sub
%>  


Hopefully that makes since.
