Embed Flickr images

One functionality i would like to see is Inserting flickr images, similar to youtube videos, user just pastes link to pic... and has option to choose size and to open different size in Lightbox2. I think Its posibble to do without Flickr API...

Available Flickr image sizes:

s small square 75x75
t thumbnail, 100 on longest side
m small, 240 on longest side
- medium, 500 on longest side
b large, 1024 on longest side (only exists for very large original images)
o original image, either a jpg, gif or png, depending on source format

Thx.
