CaptchaSaver.dll is not saving the image "as it is"

[helpot80]

It looks like CaptchaSaver.dll edits or alters the image when it tries to save, it removes or adds some bytes here and there.

i need to save the captcha as it is given on the website without any kind of processing, so how do I go about it?

I can not use wget since its recaptcha

what is wrong with recaptcha?
it makes screen shoots of captcha and save it.
