New Features Suggestions

Hi,
thanks for a nice plugin.
I have suggestions that would make this plugin very useful to our needs:

1. ability to include sub-folders automatically
if path is: wp-content/uploads/my-images/ , then it fetches from images also in the sub folders like my-images/a , my-images/b, etc.

2. ability to be able to specify which size of image to use
– add a dropdown from available wordpress image sizes.
(right now, it fetches any image in the folder, regarding of size, so it also displays thumbnails, or original sizes, etc.)

3. ability to add more than one folder to fetch image from
(right now, only one path can be entered.)

4. ability to add a link on the image
admin would select what link to use:
– dropdown menu: No Link, Custom Link, Linked Post
No Link: no link is added on the image
Custom Link: a custome URL entered by admin
Linked Post: if image is linked to a post, link to post url

Cheers!
