Pictures instead of video. How ? UI7

In ui7 I get 30 sec’s of video from my cam, would it be possible to make vera send a few pictures instead ?
In ui5 I was able to make it send 2 to 6 single pics with some interval e.g. 1/2- 2 sec’s and upload through vera alert.
How can I, at least shorten the 30 sec’s ?
The thumbnails in ui7 is useless, and you have to close every single to go to the next. I wish they would make an arrow, as in ui5, to go to the next, and better thumbnails.
