JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Could you please provide us more information on this? I'm not quite sure if I understand it correctly.
The form works when photos aren't uploaded? The forms works when you are not uploading photos? But if you do upload images, it breaks? Or are you getting any error messages?
I cloned your form, and uploaded an image for the first upload field you have (this is because it is required). I then click the submit button and I was redirected successfully in the thank you URL.
Please do provide us more information of the problem you are having.
