I cannot upload photos in mylot?

Just check if your photos are too large. I dont know if mylot keeps a restriction on photo size but it is always easier and faster to upload small size photos. To make a photo small you can open it in paint and save as .jpg file. THis will help if the photo is from a digi cam or something like that. When you upload photos you read the instructions mylot gives about the photos you can upload. Hope this solves your problem
