    How do i validate image uploads so they must be 500 x 500 pixels?

    Asked by recordunion on February 21, 2013 at 05:35 AM


    I want to add to make it so only 500 x 500 pixel images can be uploaded into the form.

    I found in settings how to specify the image format.

    However, i was unable to find where i can specify a specific image dimension.

    Any help would be appreciated!

    Hello Fredrik. Unfortunately our file uploader tool can only specify extension formats but has no ability yet to set specific metadata rules for individual extensions. This is a good feature though so I will pass this along to our developers but I can't give you a timeframe to when it will be implemented. If you have any concerns, please don't hesitate to post again on our forum. Thank You!

    Hi, I would suggest you create a new post to your inquiry. You can do it here http://www.jotform.com/contact

    The OP had a different request, it is on the dimension of the uploaded image files.

    Please create a new post and we will attend to it as soon as we can.
