wordpress image resize

[familyguy1]

Hi all,

I'm a complete newbie when using wordpress, but I'm trying to smarten up my scouts website. we have four images in a row for beavers, cubs, scouts and explorers. Currently they all seem to be cropped somehow so they look the same size but are cut off.



however when I got to resize for example cubs, i.e. go to media libbrary > find the image, click edit image and then scale the image and reduce its size to a similar pixel dimensions to match the explorer one. when I re add that image to the page all that happens is this



i.e. it seems to no crop it but the image is the same size.

My aim is to make all four icons the same size.

I've looked at the images in mspaint and pixel width by height the cubs is infact smaller than explorers.

So what am I missing in wordpress that is stopping the image from scalling smaller.

I hope this make sense as this is all new to me.
