UploadImage: Insert Thumbnail

The "UploadImage" plugin for HTMLAREA is great, but I don't want to insert full-size images most of the time, and I feel there must be numerous others having the same issue. "img_assist" would do the trick, but it doesn't work with HTMLAREA. Bringing the power of those two projects together would make WYSIWYG Drupal unbeatable.

I tried to mess around with the code but found that the project is way too complex for me. So I decided to post a feature request...

* I really miss an option to choose between the image sizes I defined in the image module and to choose whether the inserted thumbnail should be linked to the original node.

* It would be *really* great to optionally add a caption to such an image that is being displayed below it. (Just like the thumbnails in Wikipedia...) Isn't it possible to handle this as one object in the editor, so that the caption can only be edited by using the properties dialog?

* It should be possible to choose whether this object should be centered, aligned left or right. Text should float around the (aligned) object, and the margin should be controllable somehow - by stylesheet or by properties dialog.
