The following code can be used to match all img src in the source text and to populate list with value of src attribute.

C#

string sourceText; 
var imgSrcMatches = System.Text.RegularExpressions.Regex.Matches(sourceText,
            string.Format(@"<\s*img\s*src\s*=\s*{0}\s*([^{0}]+)\s*{0}","\""),
            RegexOptions.CultureInvariant | RegexOptions.IgnoreCase | 
            RegexOptions.Multiline);
List<string> imgSrcs = new List<string>();
foreach(Match match in imgSrcMatches)
    imgSrcs.Add(match.Groups[1].Value);
