Re^3: download JPG series with error-handling

To be really safe here, you might check for a success code (I think it's 202, but don't " me) rather than trying to think of all the possible error codes you might get.

Also, just to throw another wrench in, just checking MIME type might not be good enough. What if the error "page" you get back is itself actually a jpeg image? I've seen that before. Don't know a way around it unless you are also checking the error code (and the webmaster configured the server sensibly to send back error codes).

All 200s are successes. 200 ("OK") is the usual case. is_success (on the return value of getstore and getprint) checks for a return code in the 200s. But as moot mentioned, some servers return success (200) with an HTML message instead of a 404 (with or without an HTML message) when an file cannot be found. That's why I mentioned checking Content-Type in addition to the return code.	[reply]
