I can't seem to upload any pictures,

[Almondo]

Hello, I've been trying to upload pictures but can't seem to make it work. When I go into my account, open the picture folder, add pictures, it gives me an option box, from computer or internet site, nothing seems to happen from that point. From computer option is greyed out. I'm using an iPad, does that make a difference ?

Thanks in advance from a computer numpty !
