Pattern

regexengine-agnostic
(?:https?:\/\/)\S+\.(?:jpg|jpeg|png|gif|webp|svg)   (flags: gi)

Raw source: (?:https?:\/\/)\S+\.(?:jpg|jpeg|png|gif|webp|svg)

How it works

(?:https?:\/\/) groups the protocol options without capturing them — useful when you only care about matching, not extracting. \S+ matches the non-whitespace URL body. \.(?:jpg|jpeg|png|gif|webp|svg) matches the dot and extension via another non-capturing group. The pattern has zero capture groups; switch to `(...)` if you need to extract pieces.
