Photoshop and 'actions'

I have read about actions and have seen lots of photos which had actions applied to them, but never really understood and never tried to find out more about actions on Photoshop - decided it was in the too hard basket and left it there. Until I couldn't sleep last night and saw this 'action' which transformed a photo into a 'sticker'. I clicked on download........then got very frustrated because I couldn't open it or find it on my computer. Opened Photoshop and went through the menu, looking for actions. Found it under Windows on the menu. Clicked and the window opened, and there was the one I downloaded. Clicked on it........nothing :( Opened a photo, clicked on it again......nothing...........luckily I saw the little typical 'play' icon, clicked on it and saw the photo changing!!!!!!! So easy, so simple to use. I want more!!!!!!!!!!!!!!!!

Thought I'll give this a try again with a photo of the ferry

Nearly worked except for the beach in the centre! I do like the colours
