I am looking at writing a Java web application on Google App Engine. I want to be able to upload and serve images from the app but just realised that the Datastore have a 1MB limit. This is slightly too little for decent pictures. Is there an alternative way you can suggest of doing this? Perhaps storing those as static content rather than in the Datastore but there seems to be no API for this.

    Now it is possible on GAE. Simply you have to store your files in Blobstore. You can upload your files like this:

    <body>
<form action="<%= blobstoreService.createUploadUrl("/upload") %>" method="post" enctype="multipart/form-data">
    <input type="file" name="myFile">
    <input type="submit" value="Submit">
</form>

    And then to serve file from servlet:

    public void doGet(HttpServletRequest req, HttpServletResponse res)
throws IOException {
    BlobKey blobKey = new BlobKey(req.getParameter("blob-key"));
    blobstoreService.serve(blobKey, res);
