Hi, Natasha and Bev,
Thank you for informing us about the problem while uploading photo with .jpeg extension. I am going to file this as a bug such that engineering can get it fixed soon. For copy listing, the feature is currently in the feature queue list, it will be prioritized in the next big release which will be happening between two to three months from now.
As for now, the engineering team is working on releasing features that will drive more sales to sellers. These include subcategories, Google Merchant, social sharing, Blog widget and store sections.
We will get to those features soon!! xx
