it couldbe their sizes are to big to upload or the format is wrong? try taking your pictures into the paint program and then using the size settings reduce your pictures by 50 percent it should say 50% on the top line and then the bottom line should automatically go to 50 then click save and then go to Listia and try to upload your pictures again. usually when you cant upload pictures or it takes a really long time it is because they are being saved to large or the saved file format is wrong make sure they are being saved as gif.,png,jpeg(jpg), that way they are correct. this should help.
