Hello I am still learning about iphone application. I want to upload the images which I have taken from iphone camera, to the server database. I have used base64 algorithm for that. The problem is it takes 5 minutes to upload 10 images. So, is there any way to compress it and then convert it into base64, because my server is taking input in base64 string.And it is very time consuming if user upload more pictures. So please help me for that. Thanks in advance for help.
