The system I use doesn't have lookbehinds, so I can't experiment and definitively say why your lookbehind attempts were failing. The \S is not standard in REs either. A standard ERE that matches a string starting with http:, containing /pic/, ending with jpg, and containing no spaces is:
Code:
http:[^ ]*/pic/[^ ]*jpg

This same string used as a BRE produces the same results, so I would just use:
Code:
grep -o 'http:[^ ]*/pic/[^ ]*jpg' file
