Reading urls only from a text file

I have a text file having multiple urls with other information of the url.I want to download images from all the urls. How can I read the txt file and save the URLS only in an array to download it? I want to use C=textscan(fileId,formatspec) What should I mention in formatspec for URL as format? My text file has the content shown as below:

ID: 262
Name: VD0289 CUT OUT BACK DRESS
Image: http://dwimages.com/images/product/1/VD0289_VD0289_(4).jpg

I would use regular expressions instead of textscan(). Something like this should do it:

str= fileread('/path/to/your/file.txt');  %read in text file to memory
urls = regexp(str, 'http(\S+)(\s*)$', 'match', 'lineAnchors');    %find urls
