Script to scan a folder and embed images into html as base64

[ChrisBair]

I'm trying to get web pages into a database, there isn't any storage available to store the images (among other problems) so I'm being forced to convert the images to base64 and include them into the web page as encoded text. 

I started with the script on '?do=embed' frameborder='0' data-embedContent>> and soon found the base64 encoding function on  to do it all inside autoit. My problem is I need to be able to scan a folder, look for the image tags inside the html to find the image and replace the image tag with the base64 data. 

So far as I can tell, the image tags are the only one with the SRC attribute as there aren't any javascripts so it should be possible to Regexp for src="images/image.gif" and get the filename.

This is what I have so far:

#include"Base64.au3"
$file = FileOpenDialog("Base64 Image Encoder", "", "Images (*.png;*.gif;*.jpg;*.jpeg;*.bmp;*tif;*.tiff)", 1)
If @error Then Exit
$tmp = @ScriptDir & "\temp.txt"

$type = StringSplit($file, ".")
$name = StringSplit($type[$type[0] - 1], "\")
$name = $name[$name[0]]
$type = $type[$type[0]]
FileOpen($file, 16)
Local $sFileRead = FileRead($file)
$Encrypt = _Base64Encode($sFileRead)
FileClose($file)
$out = '<img src="data:image/' & $type & ';base64,' & $Encrypt & '"/>'

$loc = StringReplace($file, $name & "." & $type, "") & $name & "[" & $type & "].html"
FileWrite($loc, $out)

it does an OK job of opening a single image and then saving a html with the image data, but scanning a folder (recursively), pulling the reference and then injecting the code back in is beyond me.

I've attached some example files

I was able to get this going, for future reference, here is the finished script (it's terribly messy but it did the job!)
