How to search for all occurences of a string in a text?

[marc --]

Hi,

I have a series of texts, each of which I want to search for the occurence of 
links to images. From each text I want to extract image filenames that end on 
one of these strings:

.gif,.jpg,.jpeg,.png,.bmp

Searching a text containing the string 

<img src="http://my.domain.com/path/to/images/testimg.gif";>

would give me testimg.gif,

searching a text containing the strings 
<img src="http://my.domain.com/path/to/images/testimg.gif";>
<img src="http://my.domain.com/path/to/images/testimg.jpg";>
<img src="http://my.domain.com/path/to/images/testimg.png";>

would give me 

testimg.gif,testimg.jpg,testimg.png

I think REFindNoCase is most suitable for this since it's the only CF function 
that lets me search for multiple occurences of a pattern I know of. I can't get 
it to match _all_ occurences of the string I'm looking for.

The regular expression I use:
(<img src ?= ?[""|'][https?://]?[a-zA-Z0-9_\-/\\\.^\.jpg]+\.jpg)\s?(\1)*

I do this:
REFindNoCase(RE,string,1,"true") where RE is the above regular expression and 
string is the string containing 3 <img> tags with an .jpg resource.

This gives me an array containing the starting position and the length of the 
_first_ element in the string that matches with the regular expression. I can't 
get it to include all matches in the string.

Is my regular expression wrong or is it not possible what I want?
