Hi @Anonymous,
Could you please share a bit more about your scenario?
Could you please share a screenshot about your app's configuration?
Further, how do you store/upload multiple images on the same form within your app? Do you want to upload multiple images into your SQL table once time?
Currently, there is no direct way to upload multiple images into a SQL table once time wihtin PowerApps. As an alternative solution, you could consider take a try with the follownig workaround:
I have create a SQL Table on my side, the data structure as below:
Note: The BlobData column is a Image type column in my SQL table. The FileName column is the Primary key in my SQL table. Please also make sure that there is primary key within your SQL table.
- Create a Image type column within your SQL Table to store the uploaded images.
- Add a Add Picture control and a "Add Pic" button control within your form, set the OnSelect property of the "Add Pic" button to following formula:
Collect(UploadPics,{Name:Now()&CountRows(UploadPics)&".jpg",Url:AddMediaButton1.Media})
- Add a "Upload Into SQL Table" button within your form, set the OnSelect property of the "Upload into SQL Table" button to following formula:
ForAll(UploadPics,Patch('[dbo].[TestBlobUpload]',Defaults('[dbo].[TestBlobUpload]'),{FileName:Name,BlobData:Url}))


Please check and see if the following blog would help in your scenario:

In addition, you could also consider take a try to add a Camera control (Camera1) instead of the Add picture control within your form, set the OnSelect property of the Camera control to following formula:
Collect(UploadPics,{Name:Now()&CountRows(UploadPics)&".jpg",Url:Camera1.Photo})
Set the OnSelect property of the "Upload into SQL Table" button to following formula:
ForAll(UploadPics,Patch('[dbo].[TestBlobUpload]',Defaults('[dbo].[TestBlobUpload]'),{FileName:Name,BlobData:Url}))
Best regards,
