Web Image Editor

Hello. I am looking for a web plug in. Flash is preferred but I am open to other technologies. The user selects the type of file to upload. (File types are controlled by an xml config all files are image that are determined by certain specs.) system uploads the image and checks that the measurements and dpi is correct based on the values in an xml file. The system displays two sets of lines (one cut and one safety margin) over the image. The location of these lines is determined by the xml file. In a certain case the lines will need to be cirlces. The system allows the user to place text over the image and save it. Some text needs to be rotated. Text placement can be either dymanic or determined by an XML file. When completed the system will save the file on a server or upload the file to an FTP server or zip the files and email them to an address. Only one of the options must work. Thanks, -Jason
