I just purchased a group pack of background images from Shutterstock (.eps file). I don't have Adobe Illustrator. Is there a cheap program I can download to separate these individual backgrounds?
Inkscape can handle EPS
Initially you need to find out where ps2pdf is on your machine or install it. It's in the Ghostscript lib directory, which is probably something like C:\Program Files\gs\gs9.09\lib.
If it is not installed you may find a current release of Ghostscript for Windows on their download page here.
Then you need to add this to the system Path in Environment Variables. To navigate there on Win XP, Vista, 7: Start button > Control Panel > System > Advanced > Environment Variables. In Windows 8.1/10, right-click on This PC, choose Properties > Advanced system settings > Advanced tab > Environment Variables. Scroll through the System variables in the bottom panel, and select Path, click Edit. In the ridiculously small edit box provided add a semicolon to the end of whatever is there at the moment, and then add C:\Program Files\gs\gs9.16\lib (or whatever it is on your machine). Note -- There should be no space between the semicolon and C (the start of the path).
You will also need to add the Ghostscript bin directory after another semicolon to the system Path. (This will be the same as the lib directory, but ending in bin rather than lib - for example: C:\Program Files\gs\gs9.16\bin)
Note that updating to a new version of Ghostscript will install to a new \gs directory, but will not erase the old version subdirectory or update the Environment Variables.You'll need to delete the old directories and Environmental Variable paths if you want to make use of the newly installed version (with the new directory and paths). Also note that if you have a 64-bit system, and you install the 32-bit version of Ghostscript, the paths will be C:/Program Files (x86)/...etc., instead of C:/Program Files/...etc.
There are lots of possible tools, I'm including illustrator so that the list is more complete. A non-comprehensive list in alphabetic order:
You can also edit the bounding box with any text editor in existence. Heres an example
