In the one that I built, I used techniques that I am not allow to publish. It is outside of component rules to upload images into the image db. I went to go and fix what is broken in the marketplace component. I downloaded the original source and started looking into what would be wrong. I don’t see why this does not work. It seems to work fine for me.
You deleted the original post, can you explain the problem again? Is it that you cannot save the image as an image, but rather base64 encoded images? or is it that you cannot guarantee there is an image and you save blank stuff all the time because people save without actually signing?
