sql server and action script

yes, and yes.

is it possible to insert and retrieve images from sql server using actionscript. you'll need server-side script to query your database and you can use the flash urlloader class to call your script. also is it possible to create a flash scrolling gallery based on images stored in a database and everytime an image is added it is displayed in the gallery. load the data using the urlloader class and then load the images.  periodically query the database for new images if there's no direct way for flash to know a new image was added.
