(I do not have the code on me at this exact moment to show).
I've built something with HTML5 and CSS3. Everything works wonderfully except on some peoples computers (everyone has IE10), the image files are being stretched vertically ?
This is being built for my company (internal)...Is there a reason why this would happen on only some peoples version of IE10?
Thank you,
Nick

Answer 1

Please Check with the css as shown below,
img.someClass{
max-width:100%;
width:auto
}

Answer 2

What did the trick for me was setting a max-width at something like
max-width: 110px;
and afterwards a width:100%;
images were nog not stretched anymore
UPDATE: nvm, this caused the img to have a width of 0 on Firefox
