I have solved my problem! The iphone was taking the images at a resolution that made the file size too big. I changed a few settings and now all is good. I do have another question tho.
I have a one (pod) to many (carts) relationship. When making a new cart post, in the form there is a dropdown to select the pod that the cart belongs to. The only way to arrive at the make a new cart page is from a button on the pod that the cart will belong to, so I already know what pod to assign the cart to. Is there a way to automatically assign this without needing a dropdown?
go to cartpodfinder.com
click a marker on the map, then click the link that pops up
click make a new pod button
login with donna tello pass blahblah
the pod-cart dropdown is in form.
