Is there any way to standardize the size of photos that are uploaded into a form?

Some photos users upload are SUPER large and some are tiny.  Is there a way to make them all the same size?

Unfortunately, there is not a way to set the size the images needs to have at the moment of uploading them, what you can do is only set the limit in the file size that can be uploaded, please check this guide to get more details about it: Changing-the-File-Upload-Size-Limit

If you want we could escalate this thread to our second level as a feature request, so our developers may evaluate this and if there are more users requesting this same feature then it may be implemented.
