I've changed all my image filetype to .gif because it seems that for some reason it only supports this image type.

Now the size of my pictures are not all 100x75 like the placeholder.gif

Even if they are, they're too small.

So my question is;

What are the things that i should change in .css to make the images appear to be the size i want them to be?
