Image Uploading with Classic ASP

"But I need it to work in 64bit!" Why? You will not ever be able to load any 32 bit DLLS into a 64 bit process and you will need to go out of proc if you need to do such communication - is that what you want? What do you plan to do with your extra address space?

A topical blog post regarding what you're trying to go 64 bit for is this one by Rick Byers

If you really do believe this to be a good investment of your time, there's an article here on the internals of 64 bit COM which might help in figuring it out for yourself from first principles.

(I harbour similar instincts to go 64 bit ASAP and be done with all that legacy <64 bittedness, but sometimes things arent broke.)

Do not apply an explicit width or height to the image tag. Instead, give it:

max-width:100%;
max-height:100%;

Also, height: auto; if you want to specify a width only.

Example: http://jsfiddle.net/xwrvxser/1/

img {
    max-width: 100%;
    max-height: 100%;
}

.portrait {
    height: 80px;
    width: 30px;
}

.landscape {
    height: 30px;
    width: 80px;
}

.square {
    height: 75px;
    width: 75px;
}
