The captcha is sent by the server as PNG iirc. (it's generated on the server side)

there is some old tools that can read the captcha then write (Like auto login tool)
but most of it's links were died so tell me if u need that tool cuz it will need some time ;)

well you're wrong dude, captcha is sent as PNG by the server, check [Only registered and activated users can see links. Click Here To Register...]Quote:

well it's a part image and part is normal characters (or digits)Quote:
Or if it's a full image png so there isn't any tool or project can read it as it's png pic
but anyway i don't look for it Cuz of if the gateway give the image captcha as a digits then the client convert to png pic so there's a way to make a tool to read the captcha (from collecting the data wich coming from gateway to client) but if the gateway is the creator of the png so u can't by anyway ,,
But i was in past using a tool wich read the captcha then write it and click confirm and login (as auto login tool) .
i don't read
[Only registered and activated users can see links. Click Here To Register...]
well , but i got that the gateway send the image digits to client then the client convert to png .

A real good captcha can't be avoided, unless you make a good recognizer but It will be a very slow system...

In either case, a decent ocr system would do the job

@topic i will check now :)
good captcha can avoided as isro before there were more than 1 tool and gold botters was using it , so joymax knows that captcha won't make anything with those tools wich read the captcha so they delete captcha and make auto login .Quote:

SRO doesn't use a good captcha. A good captcha is almost by definition a captcha that can't easily be recognized (using OCR/captcha breaking applications).Quote:

Anyways, I'm pretty sure it's only a PNG. Joymax wouldn't be so stupid to send the captcha (or a part of it) to the client as plain text.
Like Drew said in his thread, it's just compressed (using an algorithm specifically designed for images) and packed (using ZLib).
