ok, i've written this regex:
/(https?:(?:/*\w*\.*-*)*(?:\.gif|\.jpg|\.bmp|\.png|\.jpeg))/i

i've tested it on rubular.

and for this example text:
<p><a href='http://sub-domain.domain.net/path/folder/figurename101...
target=_blank><img style='float:left;margin:8px' border=0
src='http://sub-domain.domain.net/path/folder/thum/figurename1010...'>...
some text</p>

rubular outputs me this:
Match captures:
Result 1
1. http://sub-domain.domain.net/path/folder/figurena...
Result 2
1.
http://sub-domain.domain.net/path/folder/thum/figurename1010...

but in my code:
matchdata =
text.match(/(https?:(?:\/*[a-zA-Z]*\.*-*\d*)*(?:\.gif|\.jpg|\.bmp|\.png|\.jpeg))/i).captures
puts matchdata.size

size prints me "1".

am i capturing wrong?

use text.scan() which matches all occurences

p
text.scan(/(https?:(?:\/*\w*\.*-*)*(?:\.gif|\.jpg|\.bmp|\.png|\.jpeg))/im)

=> [["http://sub-domain.domain.net/path/folder/figurename1010...],
["http://sub-domain.domain.net/path/folder/thum/figurename1010-thumb...]]
