Many people still seem to not be aware of EXIF data and the information it provides anyone that wants to view it. EXIF data is attached to image files as well as other files and provides all sorts of details from file creation time to exact GPS coordinates. This is the type of data that was extracted from an image uploaded by Vice Magazine that gave away John McAfee’s location when he escaped Belize. On Backtrack Linux there are numerous tools to extract EXIF data including exiftool which is written in Perl and easy to use. Below we will describe exiftool, which is located in /pentest/misc/exiftool/ or /usr/bin, and provide examples to show how easy it is to use.
I had one of my clients call me today and say he wanted to make some T-shirts with his logo picture, that I was using on his website. I said OK and sent him the .jpeg file. He called me back twenty minutes later and said his T-shirt guy wanted the image in a vector graphics format. Now I am not sure why the T-shirt guy wouldn’t have the software to convert it however thats not my problem. In any case I always like to try to find free software to complete tasks like this. I have used a program called Inkscape in Linux many times but I had no idea what to do in Windows. Fortunately, there is a version of Inkscape for windows.
I recently wrote an article on how to batch resize images in Adobe Photoshop CS4. If you have been reading any of my recent articles on the site you will know by know that I had a laptop hard drive crash and I lost some settings. One of the settings was the Photoshop Action I had created to batch resize images. Anyhow while configuring the Action I decided to play around more with Photoshop to see if there was another way to resize images and sure enough I found a better way if you don’t mind saving the images as JPEG’s instead of GIF’s.
One of my sisters recently sent me a link to a photo gallery slide show online at kodakgallery.com. The gallery is in a flash slideshow format where you can scroll through the pictures, etc. I wanted to save a couple of the pictures to my desktop to upload to a personal photo gallery however within the flash application you are unable to right click the image and save it to your desktop. It took me a second to figure out but you can actually save these images to your desktop by exiting the slide show and viewing the images outside of the flash application.
When you are viewing a Kodak Gallery in the slide show format it will look similar to the below.
There are a ton of shareware applications that will allow you to convert image files to PDF for free however they typically leave text about their product all over the PDF until you pay for the application. I was able to locate and successfully convert some jpeg files using a freeware application from CNET download center. It is very easy to use however you have to make sure your images are a certain size before converting or it will not work properly. Below are step by step instructions on how to convert multiple image files into one multi page PDF document. Make sure that each of your image files is 600×800 pixels in size or smaller if you want the entire image to fit onto the PDF page. You can also adjust the “Page Size” setting if you prefer to have larger than normal PDF pages.
