if there is a next button when you look photos

[ownmake3]

i come from China,i like this software.

there is more than 10 pngs in the folder,they are continuous files,such as 1.png 2.png 3.png....
I think that i can view them without the keyboard。。。。
just like

it is used to be disappeared only when mouse move on it will be appeared.

if there is 100 pics manga ,we only enjoy it just click the mouse.

thanks.
