+Easy to use and configurable library to **Pick an image from the Gallery or Capture image using Camera**. It also allows to **Crop and Compresses the Image based on Aspect Ratio, Resolution and Image Size**.
+
+Almost 90% of the app that I have developed has an Image upload feature. Along with the image selection, Sometimes  I needed a crop feature for profile image for that I've used uCrop. Most of the time I need to compress the image as the image captured from the camera is more than 5-10 MBs and sometimes we have a requirement to upload images with specific resolution/size, in that case, image compress is the way to go option. To simplify the image pick/capture option I have created ImagePicker library. I hope it will be useful to all.
