Hi, I'm currently writing an image management adapter for Zope3. It's goal is just to create and store thumbnails "on the fly" when an image is requested with an additional specific traversal name (for example, "myimage/thumbnail" will create a thumbnail of a given predefined size, while "myimage/200x200" will create a copy of the original image reduced to 200 pixels). These thumbnails are stored in the original image annotations.
Everything seems to work fine, except for a little thing : I've created a specific widget so that, when an image is uploaded, a thumbnail of the new uploaded image is immediately displayed next to the "data" field upload button. But when the form is displayed, a "DatabaseConflictError" is visible into Zope's log, even if everything seems to work correctly from a browser's point of view. I'm not completely sure to understand what DatabaseConflictErrors are, so any explanation about this kind of problem would be greet. I'll just add for your information that I'm using ZEO...
