My Images are being stretched …. What is wrong

That does not doit
I changed the image size in the html for the post. and nada.
something is over writing. some overlay setting problem.
something

Someone knows what is happening. Most of my pics are ok.
it is only the pics i put in today.
all of them.

That fixed it.
The only problem is this is a viral problem of sorts in that the problem has occured is 3 more post all with todays date.

Am I doing something wrong as I insert the images
I use the image uploader and it has worked fine up till today

I am such a rookie. I have no idea what to do. I am not sure what you are saying. I copied my css stuff
