Why not give that option to the users of this software, since we are the ones paying for it? I don't see a huge enough difference between 3900 px and for instance 5500 to be 'hiding' the option for us to increase it when we need it.
I think you misunderstood what I was saying. For example I have my Maximum Attachment File Size set to 150 KB and my Maximum Attachment Image Dimensions to 1280x960. Then when I upload a image that's 3580x2538 and 2.35mb, I get a file to big error message. What I'm looking for it to do is resize the image to be no more then 150kb, instead of rejecting it.
I have my vB forum setup to accept file sizes up to 9600x7200 and 8mb, it'll then take that image and make it no more then 150kb / 1280x960. Granted it's server extensive, however my users aren't techy and don't know how to resize the 4-5mb images they get off their cameras. I'd rather have my server work a little harder then them not posting their images.
BTW I checked my stats and last year we had ~6,000 attachments.
