Did you try finding the image for this product in the image library where you uploaded it?
No, what I meant is to go to Content -> Images, find the image that is associated with this product item and delete it from there. Then the product will appear without image. I hope this makes it clear.
You would have to extend the existing ImageField, for example to add a checkbox for deleting or some button that would clear the field by inserting a Guid.Empty or an empty string in the custom field. I plan to release a second part of my blog series outlining how to use the image picker dialog. I will probably extend the existing ImageField to add this feature.
Yes, the plan is to include all three points you outlined and maybe some more. Stay tuned.
I'm currently working on this. I plan to release a blog post about creating a Sticky Notes module for your Dashboard today and this will be the next blog post I'll be working on.
I need the same functionality. Is it ready to use? If not,, please give me some indication how to do it by myself
