Alert if image size fails validation
I'm using UE4.01 to allow users to upload their on photos into their own directory. I want to prevent images above a certain Pixel Width being uploaded.
The point of this is to minimise my bandwidth utilisation from users uploading large digital camera photos, as they are likely to be in excess of few MB.
I realise i could ask the host administrator to change the file size upload limit in the php.ini file, but this could be more a more flexible and page friendly solution if existed.
Can this system validate the image dims for Width & Height?
If so, what's my approach please?
