Why the images are not showing in form?

Hi can you please tell me why my form is showing question marks not my actual pictures please ?

I checked the images in headers in your form and apparently, the links to images are broken. Unfortunately, I'm not sure how that happened, did you try re-uploading the images?

Hi,

On further checking I have lost all images in my account across all forms ?????

Can you please look into this, this is a huge amount of time to fix

amd_forms - not sure why it came up with that name - Im logged in as amd_forms

Did you re-upload the images? 

I have just checked your form and noticed the images are displaying properly on your form https://form.jotform.co/amd_forms/luxe-candle-order 

I have also cleared your forms cache, please check and let us know if the issue persists.
