C# regex parse to pull photos from markdown?

Photos in markdown look like ![alt text](src). I'd like to parse a block of markdown, pulling all photo sources into an IList<string>.

I know regex is probably the answer, but it's like an ancient cryptic language to me... how would I go about parsing out all photos into an IList<string> using C#?

Example text

When I say "Japanese-Chinese" food I'm not referring to some new type of restaurant      serving both Japanese and Chinese food. This means the restaurant serves Chinese food   prepared for Japanese tastes.

This is **subuta** -- sweet and sour pork, this one photo showing the meal set (tenshoku in Japanese). It's one of many Chinese dishes this restaurant serves... and they have **A LOT**!

Something like this, should work:

!\[.*?\]\(.*?\)

have a play here, to see how this works:

var matches = new Regex(@"!\[.*?\]\(.*?\)")
    .Matches(str)
    .Cast<Match>()
    .Select(m => m.Value)
    .ToList();
