This is a security feature built into some captcha systems that only allows a captcha to be downloaded once. What you need to do is grab the captcha from your cache (usually memory cache).
In Firefox, it basically all comes down to the internalSave() JS function, which allows you to save an image to you hard drive from your memory cache. I gave up on trying to do it with imacros, and moved to autoit to accomplish this task. Very little documentation to go on and it can be very tricky stuff.

Good luck!

i thaught there was something like that, even went through the jquery docs to see if i could find something like capturing images or stuff like that... seems like it doesnt work out of the box, ill dig into this tonight and if it doesnt work, guess ill have to find another way to bild a bot suited for my needs...
u were right, it really comes down to this function, but I guess you dont have access to it outside of firefox right?
it would really be a little too much to write an extension only for this purpose, or maybe it would be possible to modify imacros in a way that it works...

How do you do this with the Imacros scripting edition? (and through the imacros browser). Ive tossed quite a few macros for this exact reason.
For some sites - the captcha is served up by a php script - so when Imacros tries to select the image on the recorded macro - it generates the second captcha image via the php call, which is of course incorrect... We want the image as it was when the page was loaded the first time around (and obviously stored in the cache....)
Any hints would he HIGHLY HIGHLY appreciated...
I wonder if this has a related setting in IE
Thanks mate
cheers

hi,
I am using imacros with various sites and it solves captcha really nicely for all kinds of captchas including recaptcha, php captcha etc.
instead of CONTENT=EVENT:SAVEPICTUREAS
use
CONTENT=EVENT:SAVEITEM
this downloads picture from the cache of the browser and does not load the picture again so captcha image is shown correctly
Hope this helps
just my 2 cents

Hi if someone can help me with this I would appreciate it greatly and am willing to pay for the right answer.
So I made a script / bot with Imacros but I am having a problem similar to what is being described in this forum post.
Basically I will load up a bunch of URL's on the same page to do commenting and when I go to load the captcha is loads correctly the first time around but when I go to load the second page in the .csv file and it goes to load the captcha it displays the first captcha and the second and looks like this
fAe#8 [EXTRACT]it2Yj
so the first captcha is fAe#8 and works fine but the second page is loads the above sequence.
I am not sure where the error lies. I dont know if its a cache issue with firefox or if its with decaptcher.com or the script, if someone knows, please drop me a line. Thanks.

I would be interested in this as well, i have fought day and night to figure out the captcha portion with imacros, so just installing the plugin will disable the firefox default caching mechanism? Any chance i could see how you setup your imacros script?
