  1. Create RequestLimiting plugin

    A RequestLimiting plugin would prevent a single IP address from requesting more than a certain number of images per minute.

    DOS and DDOS attacks are already blocked by GDI's memory allocation requirements, but this would allow more granular control.

    • Make it easier to give you money.

      We're now using your plugin in production and want to get a license even for the 'free' version to support your work and of course get support should we need it. It's obvious now that I found it on the plugins page but it seems like it could benefit from some "buy" option from home page or licensing pages.

      • Create SignedRequests plugin

        Create a plugin that blocks all image resizing requests except those HMAC signed with a key. Since the signing has to be done server-side, this would only be useful for ASP.NET apps, and only server-side pages could generate image resizing links.

        • Offer an MVC ActionResult as an alternative to using the HttpModule.

          ASP.NET MVC is intrinsically limited (by bad design), and cannot achieve the same performance as an HttpModule can, because it cannot pass a request completely back to IIS for handling.

          In addition, an ActionResult cannot control which routes are directed to it, which means the CloudFront, Image404, ImageHandlerSyntax, and ImageFolderSyntax plugins cannot be supported from the ActionResult.

          This limitation also means that the developer will be responsible for creating routes for every syntax he wishes to use, every plugin he wishes to use, and every file extension (or lack thereof) he wishes to support. Plugins which will probably need separat…

          • Add &bounds=canvas setting: Width/height constrain the canvas (output file) size, not the image (inner photo)

            Add &bounds=canvas setting that indicates that width/height specify the canvas size instead of the image size.

            Canvas size and image size differ when using borders, padding, margins, drop shadows, and rotation.

              • keep doing exactly what you're doing

                ImageResizer.Net is freaking amazing. It's my goal to convince my frugal CTO to purchase an enterprise license immediately. I can't help but express how awesome this plugin is, and I plan on purchasing it for my own side projects as well.

                Thanks for making a killer product.

                • add properties specifically for movies in the ffmpeg plugin

                  When thumbnailing through the API, the Bitmap object after loading a source image has properties such as width, height, colour depth, etc. But the ffmpeg plug-in isn't able to expand on this as-is. It would be great to be able to access the duration of the movie as a property. (We store this meta info with the original file, and display it alongside the thumbnail.)

                  • Rename Watermark plugin to something more generic

                    The (wealth of) features that the Watermark plugin provides are by far more than just watermarking. I would suggest to rename it to something more generic like "Overlay", "Composition" or "Image Merge" plugin.

                    This will help new users to better understand what this plugin is useful for and that it is capable of much more that just putting simple watermarks on photos and images.

                      • Create a plugin to add metadata to http response headers

                        Preface: I'm an iOS developer who builds some apps against sites that use ImageResizer.

                        I have a common use case where it would be helpful to know the original size of an image at the point when the processed image is returned.

                        I often grab thumbnails to show in tables in the iPhone. When a user clicks on a table cell, I load up a custom view. Without knowing the full size of the image, I have to delay doing my view layout until I can download the full image. This can be a bit slow on some phones. If…

                        • Create ThroughputLimiting plugin

                          A ThroughputLimiting plugin would limit the amount of RAM and CPU used by the image resizer at any point in time, causing requests to queue (or be cancelled) instead of executing all at once.

                          If your application accepts batch uploads, this could be very helpful in keeping RAM usage low enough. On a 32-bit application pool, RAM usage is limited to 2GB, which equates to 200-500MB/s of resizing throughput. With 200 concurrent uploads of 20MB files each (and with a client who has an insanely fast fiber or ethernet connection), it's possible to exceed this.

                          If you're using shared hosting,…

                                High concurrent request image with a watermark arise blocking。I guess it's a bug.

                                ImageResizer.Plugins.Watermark.ImageLayer.cs code:

                                public override void RenderTo(Resizing.ImageState s) {
                                ...
                                lock (img) { //Only one reader from the cached bitmap at a time.
                                ...
                                why used lock? Replace it with below code, are you ok?
                                using (img = img.Clone<Bitmap>()) { // Clone it's watermark image replace lock method.
                                ...
                                }
