iStockPhoto: Your uploaded sample file is not a valid ZIP file

Did you get this message when you uploaded your first sample illustration on iStockphoto and you are sure, that you ZIP your EPS file? Don’t worry, the problem is not in your file (probably).

The problem is in the browser, that happens sometimes when you use Mozilla Firefox. Another problem with this browser is when you upload photo or illustration, you type in all desired information (name, description, keywords), then you hit submit, but just because there is some duplicity in keywords (or some other small problem) firefox lost all your inputs…

So my tip is: Don’t use Firefox on iStockphoto, use Internet Explorer instead!

  1. Thanks for the advice, but, unfortunately I keep on getting that error message when using IE, I’m so frustrated it’s hard to imagine, can you please please advice?

    Thanks in advanced.
    Tal.

  2. Maybe try another browser. What program did you use for creating the ZIP? Maybe you should try some other (I used Total Commander and it was OK)

  3. Thanks for being so fast.. I also use Total Commander, and I use Mozilla as a browser. In the meantime I searched googled this error, and I can see that I am not the only one with this problem. I will try with Chrome, and let you know..

  4. I am so stupid… I asked you a question, than I was desperately looking for the answer, and had about 30 tabs open in my browser.. than I saw you saying „Maybe try another browser….“ and I thought you were already answering my question. I am sorry for the mess, you can erase all of my comments now. You’ve helped me without even knowing :)

  5. zsooofja: that was good :) you found the answers yourself!

    But yesterday I have also some problems with uploading some files on iStockPhoto. I hope, that they already fixed it.

  6. Hello,

    I bumped into the same problem, only the browser was not firefox, but chrome.
    It would be only normal to make the site work for various browsers instead of redirecting us to a specific one.

  7. I feel so crazy for upload on mozilla.
    i don’t know before, the problem come from my browser,

    Thank you very much

    I use Chrome and completed the upload task.

  8. First of all, thank all of you, the Post Master & audience. Finally, I done it after 1 day try. First day I tried with Mozila but it not work, but today I try to your advice & I got it. My special thanks to you MR.Orson. Finally I’m using Internet explorer.

  9. This is the reply from iStock’s customer service team:

    This sounds like a caching issue. Please clear the cache on your browser, log out then log back in and try again.

    I’ll try it later.
