Hi BBPRess has an issue with uploading images on the first post. Very frustrating, the developer is looking into it.
Will you upload again?
Is this for Inbound Forms?
I have this retired plugin asset that MIGHT work for you. It has had many conflict issues so I took it off market. Welcome to give it a try. Otherwise you may have to use a 3rd party plugin like Ninja Forms 3, Contact Forms 7, or Gravity Forms and use one of our integration extensions to tie it into Leads.
