We provide a native commercial product for doing these things. CFX ImageCR 3 : http://efflare.com/products/cfx_imagecr
You can resize, convert, crop, etc. You can also retrieve image dimensions and more with the GETIMAGEINFO mode. Additionally, since someone mentioned it, you can also strip out the extra metadata in some image files. In fact, this is done by default with the STRIP attribute. http://efflare.com/docs/CFX_ImageCR3/reference/attributes.html#strip Finally, for those that need it we will also soon add SWF output with transparency to our list of supported formats. We constantly support and update our products.
