Can we increase the size of photos that can be uploaded?

The max photo size is only 1024kb, is there any way around that? We need our clients to be submitting high res photography.

You can change the limit that you want to allow for uploads up to 5GB file per file upload field.

To do that you would need to increase the default size limitation, and you can do it as per a guide here: Changing the Upload Size Limit

Do check it out and let us know if you have any questions along the way.
