Way back when, I described the difference between “photos” and “illustrations” at iStockphoto.com . A “photo” is a pixel based image, wheras an “illustration” is a vector file – an editable definition of an illustration. The artist combines lines, shapes and other elements, and as they are working, the editing program, such as Adobe Illustrator, renders the image from the elements the artist has created.
Vectors are cool, one reason being that since you have a description of the parts of the image in the file, you can tell software to render a pixel based version of that image at any size you want. Teeny tiny, to super huge. It knows a circle is a circle, and it can render out that circle as a 10×10 pixel image, or a 1000 x 1000 pixel image. The circle just shows up with more detailing pixels the bigger it gets. You don’t need editing software like Adobe Illustration to do something like this with an iStockphoto vector .eps . You do need software that can import vectors, and I’ll go into that down below.
Another reason vectors are cool, is because you can go in and change colors and sizes of elements in the illustration. Don’t like that box red? Make it green. Want that flower bigger? Grab the group and scale it up. For this type of granularity, you do need software that can edit vectors, like Adobe Illustrator, Freehand or CorelDraw.
What do you get?
So, when you buy an illustration on iStockPhoto, what do you get? You receive a .zip file, and inside you will, at least, find a .eps format vector file, which is Adobe Illustrator 8 compatible. In Illustrator, the designer will have specifically saved out the file to be compatible with Illustrator 8. iStock is trying to keep compatibility with this older format for many users who are using legacy software.

Also, you will receive a minimum 1900×2800 .jpg version of the vector. So, right away, if you don’t have a program that will read in the .eps vector file, you at least have a .jpg you can use in your project. Please note, some older vector downloads do not have the .jpg included. iStock is going back through and adding these to the files uploaded before this requirement. You’ll know if you will get a .jpg in your download if you can use the image zoom feature on the illustration’s detail page, as seen below on the awesome RUSSELLTATEdotCOM’s image.
You may also get other interesting things, like a .tiff file, or a .ai vector file. Most contributors who have taken the time to fill their files with extra goodies note that in the description field.
What can I do with it?
Ok, you probably know what you can do with the .jpg file. What can you do with the .eps? If you’re a beginner and don’t want to actually mess about with the contents, you can rasterize it yourself (convert it to a pixel image). From this thread:
On a Mac, you can do that in the Preview app which comes as part of OS X. If you don’t have a Mac or don’t have Photoshop there are freeware apps that do the same in Windows. It’s really simple. And free!
From the “Tip of the Week”, regarding Macs:
Open the EPS with Preview. It will automatically convert to a PDF. You can save it as a variety of other file types as well.
Those freeware apps mentioned above for windows? Here’s a google search for “.eps converter“.
But, you don’t even need to download something. Most designers, even beginners, are using an Adobe product, like Photoshop, InDesign or Acrobat. These programs will read in a .eps file. So will Corel Paint and Paint Shop Pro. In Photoshop, for example, when you open the .eps, it will ask you what size to render (rasterize) the file at.

In my example file, I have a filled star shape. You can see below, that when imported into Photoshop, it has a transparent background, which allows me to easily place it over something else. Cool! That’s not something I could do with the .jpg, which does not save transparency, and would give me a white background for this file.
Remember though, that you can’t actually edit these as vector elements in Photoshop. You actually need Illustrator to easily change the star colors (you could do it in Photoshop by messing about with selections and adding color and such).
Conclusion
Even if you aren’t a vector whiz, you’re certainly able to use vector Illustrations from iStockphoto.com in many cases. You can make your own XXL image from a 1 credit vector. Not a bad deal, and there are definitely a ton of excellent vector artists on iStock.
