Hey guys, sooooo many threads here about icloud Photo lib ... seems that Apple is not doing a good job of getting the message out to people to tell how the system works ... I have questions myself !! 1- How do I know at a quick glance if the pics I have just taken with my iphone camera have been uploaded to icloud Photo Lib and have also been Optimized for storage space ? 2- What is optimized for storage option ? It says that it saves a tumbnail of the photo on the phone ... When I select a photo to look at does it download the full resolution pic everytime and replace the tumbnail version ? If so ... does it convert the pics I have looked at to optimized storage space automatic or after a specific time or action ? 3- When I send a pic via email ... sms .. or other services does it send the optimized version that saves space on iphone ? or can I chose the size of the pic (small, medium, large ) ? 4- Do videos also get the optimized treatement when uploaded to icloud Photo Lib ? 5- When going to iCloud.com and I try to upload photos on the beta version of Photo libr on the web browser ... I always get a message that there was a network connection error .. and I cant upload nothing ... anyone else getting this ? Thanks for your feedback guys !!!
