Validating image size before uploading
This is one I had some help about ages ago, and had a page checking the the width of an image fell between two values. I now have a requirement to check the image is an exact size, so need it to check the height and the width.
I have attached a page with what I thought it should be, but doesn't seem to be.
Can you have a quick look and let me know what I have wrong? I think it must be something along these lines.
