How can I upload pictures to my albums in the order I want them to appear in?

I think it'll work if you number them, but use leading zeros (and use just numbers as the file names, not strings like "wetgfinthepool01, wetgfinthepool02" etc.

So instead of 1.jpg, 2.jpg, 3.jpg ... 9.jpg, 10.jpg, 11.jpg, and so on, do this:

001
002
003
...
009
010
011
...
098
099
100
101
102

and so on. If you don't use leading zeroes, and upload say 13 images numbered 1 to 13, then this sort of thing happens:

1
10
11
12
13
2
3
4

However this is just a guess, as I've not really played with the album functions. But I know the forum handles images posted here that way, which sometimes catches people out so I'd expect the albums to be similar.

Is it possible to reorder them? I'm a non-verified account so I have to wait and see after the album is approved.

I think for me at least I delete the photo than re upload in order
