javascript - Imacros.. file by default appends extension even on mentioning the extension -

I'm taking a screenshot of one element on a webpage, but it's of .php format Saves the image in CG format (respetively in each case). How do I remove the default extension for a file?

For example

build version = 8850919 recorder = Fx tab T = 1 URL GOTO = approximate: newtab URL GOTO = http: //falcon.spectranet.com/ Llmrtg / cgi-bin / llmrtg.cgi tag pos = 1 type = input: text form = name: llmrtt ATTR = NAME: cp_id CONTENT = ***** SET! No encryption status = 1 type = input: password form = name: llmrtg ATTR = NAME: cp_pwd CONTENT = ***** tag POS = 1 type = input: submit form = name: LLMRTT ATTR = * downloadable fodder = * FILE = + _ Image WAIT = yes tag POS = 1 type = IMG ATTR = SRC: http: // falcon spectranet.com/llmrtg/cgi-bin/graph.cgi? Cp_id = 17197 & session = * CONTENT = EVENT: SAVEPICTUREAS

In this example, I get image.cgi and if I type FILE = + _ image Jpg then my name is renamed to image.jpg.cgi , how can I get a thank you from before in .cgi

Instead CONTENT = EVENT: SAVEPICTUREAS I CONTENT = EVENT: changed to SAVE_ELEMENT_SCREENSHOT This works for me in the last line, my file is now .png

  tag POS = 1 type = IMG ATTR = SRC: http: //falcon.spectranet.com is saved as /llmrtg/cgi-bin/graph.cgi?cp_id=17197&session= * CONTENT = Event: SAVE_ELEMENT_SCREENSHOT  

Everything else is the same.
