Gif image format, not jpg

[fer]

My gallery features the following problem: when I click on the images to the right and "save picture as" to save them on your PC are in. Gif. Before there were so. I like the standard jpg format. How to fix the problem?  (Only the intermediate and full-size images are the problem) http://www.sophiabushbrasil.com.br/galeria

Disable transparent overlays.
For details read the docs.

What do I get the image in full size pop-up and in jpg format?

I've browsed the docs. And checked the javascript as recomed the topic: The fullsize-pic does not pop up When clicking on the intermediate size pic. What's wrong?

But nothing changed. How do now?
