custom built image editing tool (for online)

hi, i have a website where i need users to upload photographs with the ability to edit them..... they will upload a photo into the site, or click from a list of pre-upload photos to edit this photo, it will do the editing, save the new photo and delete the original after they have finished editing them they must end up being either 300x200 or 200x300 pixels, so i need a custom built editing tool with the following features: fixed ratio crop 3:2 and 2:3 resize rotate flip preview text add blur to a selection format conversion (allow edit of gif, png, jpeg etc... but all files saved as jpegs) this can be done in flash or anything that wont require install of software on client side. please private message me with any questions
