I'd like my users to be able to upload an image by pasting it into a form.
Is this possible somehow with Rails?
I'd like to do this safely and limit to a single picture upload, not a completely open textarea.
UPDATE:
I'm looking for something like http://pasteboard.co/ that I can add into a form in a Rails app.
Also, with a paperclip hook like https://github.com/galetahub/ckeditor would be nice
Although I don't have a specific answer (copy & paste), I do have an answer regarding how to implement the uploading within the DOM:
JQuery
If you use something like jquery-file-upload, you'll be able to incorporate a GUI-based upload process to Rails
I think your question can be answered by taking this technology & applying to the specific element where you'd like to "copy & paste" the image
You can drag & drop images from your system into the example above. This is very similar to the copy & paste functionality you're seeking. I would personally look at this technology, and then apply it to the copy & paste procedure
WYSIWYG
You've referenced GMail as a great example of this -- but you have to remember they're allowing you to paste into a WYSIWYG editor
This is very important, as the upload image element will be handled through the WYSIWYG. You may be able to use this resource to help:
