I recently uploaded a vector image to Shutterstock, Fotolia and IStock. I use Inkscape to create my vectors, therefore I cannot check my files in Illustrator. Shutterstock rejected the image, saying "no bitmaps allowed", and after carefully screening the whole image, I found a small section in which I had accidently used transparency, which was likely the cause for the rejection.

To my big surprise, the same file was accepted by Fotolia and Istock. I am a little confused, I mean either my file contains bitmaps or not??? Should I resubmit the corrected file to Fotolia and IStock? Is it actually possible to replace an already accepted image?

Thanks in advance for your feedback!

It was saved as an EPS 8 file. So definitely no transparency possible. I am just really confused that IStock and Fotolia didn't notice. Maybe I'll delete and resubmit the file, I don't wanna sell bad quality vectors. I hope they'll accept self-deleted and re-submitted images 

Really? I didn't know that. I have always tried to avoid transparency, I thought that it's not compatible with the required EPS format. Being able to use transparency would make my life a lot easier!!
