Error while picture upload

Hi. When I upload picture in the form, error pops up. Please support.

Hola @Ramil_Rahimzada

Is this a free app? If so, have you checked if you still have enough storage. On the free tier you only have 100MB.

Where do I delete these pictures, so I have more free space.

You can delete the link in your data (Sheets and Glide Tables).
