You cannot prove that. They were on your PC, fully under your control for some time. You could have tampered with them. Therefore you cannot prove that you did not tamper with them. If you need to set up a legally safe solution then look for an independent third party and a way to have them store information in such a way that you can only trigger a store ...

You can do it with Firefox and 2 extensions: Web Developer and FireShot. Once both extensions are installed, go to Tools - Web Developer - Resize - Edit Resize Dimensions... . Add a new size, 4000 x 3000. check "Resize the viewport" if you want only the page content to be 4000x3000. If you don't check it, the complete window of Firefox (with toolbars, ...

It is incredibly simple to change the apparent content of anything posted in a public place & needs no great skill to totally change the meaning into anything you like… This fake screenshot took about 30 seconds in photoshop.

Proving that using technical measures is hard. What you can do is document the way you took the screenshots. One possibility is having a witness present while taking the screen shots. After taking the screenshots, you could print them out with the filenames, date, and time they were taken. Then the witness and you sign those prints. A digital version of ...

The closest thing I can think of is Problem Steps Recorder. You can access it by clicking the Start button and typing "psr.exe" and hitting enter. This tool will record each mouse-click and save it as an image, then compile everything into HTML (more specifically, a Microsoft MHT file). However this is not a video capture tool. As far as I know, there isn'...

As per Snipping Tool help file. Open the snipping tool and Hit <Esc> key to get out of snipping mode. Setup the screen. Hit <Ctrl> + <PrtScn> Perform the snip. This way, you can still get the open menus or popups or whatever is needed. However, you still won't get the cursor arrow.

An option is to use a second PC that has a video capture card installed. There are a few out there if you search that will let you input and record from computer sources like DVI or VGA. You take your first pc video out connect that to a video splitter so you can run that video to a monitor and also the video capture card on the second pc.

Print to PDF, then save the PDF as an image. I think that's probably your most foolproof method. Printing to PDF is straightforward and you've got a ton of options, conversion after the fact will maintain page layout. Conversion answer here: How do I save an image PDF file as an image? As a note: if you use the PDFCreator project available from http://www....

Camtasia. If you scroll down, in the comments Jeff says: Please, tell what tool you did use to make that kind of gif-based animated demo ? In this case, it's Camtasia, but I've used gif-gif-gif before for similar effects. Check out the Donation Coder roundup of screencasting tools for more options: http://www.donationcoder....

Specifically how it works is implementation-dependent, but in many cases the framebuffer holds whatever is currently being displayed on the screen, so the simplest way to make a screenshot is just to take that chunk of memory and write it to a file. You can often do this (on Linux) with the command cat /dev/fb0 > 'filename' (where 'filename' is the image ...

Ok, this isn't about VLC but I'm guessing the real question is "How do I easily record my desktop, with audio, preferably with a free open source app?" I gave up on obscure VLC command lines and found another piece of software called ShareX, which is free and open source. It's pretty easy: Download and install ShareX. Run it and click Capture->Screen ...

No, not using snipping tool :( In Windows 7, you may have some luck using Problem Steps Recorder, which is free and included. Either click the Start Orb and type in search "Problem Steps" then click on "Record steps to reproduce a problem", or a lot easier - Go to run (Windows Key+R), and type "PSR" Click Record, and it should be able to take screen shots ...

You could try out BrowserShots, its free ;) This will also be useful if you want to look at the site in multiple different versions of the same browser (IE6, IE7, IE8 etc), without having to go through installing each version, checking the site then moving on to the next version.

The Firefox Abduction! add-on couldn't save an image that large. If you absolutely want to save an ultra-lengthy single image and are open to non-Chrome solutions, here are a few that might work: SiteShoter is a portable app: There are any number of online web screenshot apps, such as this one

There are two issues, prove that you took the picture (not fake), and prove that the picture you took is the picture I received. The first is as noted by others of course impossible as screenshots are trivial to fake as the content is computer generated anyway. The second is much easier with solutions from comprehensive signature solutions (pgp detached ...

According to GNOME API doc, the gnome-shell (shell-recorder class) screen recorder is basically pipeline all screenshot output to a pipeline which is then encoded by GStreamer.

From how to use VLC to stream your desktop live (windows) with audio (or stream a DVD) : VLC by default comes with a "screen input" option, to capture the desktop. Unfortunately it appears there’s a bug (status: closed wontfix), so currently it can only capture video. The solution is to use DirectShow as an alternative input. With Directshow, you can ...

As of version 1.26 there's an official fix and it works fine. If you have a older version, or another program with similar issues, but the simplest thing to do is to upgrade. Unfortunately, the Windows start screen and LICEcap don't go well together, so no gif for the first part. You'll need to go to the place LICEcap is installed (type in licecap into ...

First of all, you can't. If you want to prove that you received message X from Y, ideally you would receive it in front of a notary, on their computer. Lacking a notary, an independent witness may help. This doesn't preclude that the person at the other side, that you believe to be Y, in fact isn't. So you better have them in front of you and the notary, ...

The free version of FastStone Capture will capture a scrolling web page. Works best with IE but also works with FF (it scrolls the window very slowly) and kinda works with Chrome (page is OK but it messes up the the scroll bars). There's also PicPick (use the 'Capture Window Control' command) which works with IE and Firefox though won't scroll in Chrome.

I had asked a similar question for browsers at Software Recommendations. Summary of the discussion there: http://www.icanprove.de - most general method I've seen so far. Provides a remote browser (Firefox based) that records your input, and produces signed PDFs that contain the inputs you've made and the screenshot. So you can even login into pages and ...
