Kinderloop is optimised to use the free apps on your mobile device or tablet to upload to your own private Kinderloop, images are then automatically sized to fit.
Often if your photos are held on your computer, they may be larger than the 2MB limit that we have (per photo) so its a good idea to either lower the resolution on your cameras slightly or download some free software to make the images smaller, try searching on Google for 'free photo scaling' software for your particular PC.
A size limit was introduced so ensure speed of upload was kept at optimum levels
