signature and person details

I created a visitor application where one needs to enter his details and a signiture. These are all going into SharePoint even the signature image. What I want to know is how can I make sure that a particular signature is of a particular entry row in SharePoint ?


To show the image in PowerApps in a Gallery Or Form put an image control in the gallery row or the Form datacard and point the image property to the image column.  In a Gallery this would be ThisItem.Image and in a Datacard this would be Parent.Default


If this fails it may be your image data has a " at the beginning and end.  You need to remove this.  I do this with a simple label with a formula like(In a galller)

label1.Text = Right(Left(ThisItem.Image,Len(ThisItem.Image),-1),len(ThisItem.Image_)-1)


I Then point the image control to the label




yes i use JSON. now what i want instead of showing the data:image/png;base64 i want to see the image in the sharepoint column

I don't believe that is possible in a SP list. 

can i create a link in an sp list so that when i click it it will open the image ?
