Add hyperlink to picture

I have created a page called Apps. Inside the Apps I wan to post logos (pictures only). And when user clicks on any picture it brings them to a respective page that was also created by me.
I tried to highlight the picture, click on “hyperlink” and choose the page I want to link it too. It worked but when I tried to do with the second picture which located next to the first one, the same trick does not work. Why?

Thanks
