PowerApps getting users image and upload to sharepoint

Posted on by BN-12021351-0

Hello,

I’m running into an issue while trying to implement what should be a relatively simple feature.

In my Power Apps application, users select items from one gallery, and those selections are moved into a second gallery. For each item in that second gallery, users need to upload one or more images. I’ve successfully handled this in temporary memory within Power Apps, but I’ve been unable to patch the images to SharePoint upon submission. I’ve tried multiple approaches without success.

A key constraint is that I can’t use the standard Edit Form attachment control, because the image upload button must live inside the gallery and be tied to each specific sub-item, which is itself controlled by a higher-level item within a request.

I’d really appreciate your guidance on a proper solution. I’m happy to share any additional details or screenshots that would help.

Thank you!

I’d suggest using a SharePoint Document Library instead, and uploading the images via Power Automate with metadata (e.g. RequestID, SubItemID). That way each image is tied to the parent record through metadata, not through the attachment control.

It’s much easier to manage long term, scales better, and avoids the need for complex gallery-inside-gallery handling. You can simply filter the document library in a separate gallery using the selected item’s ID from the first gallery and match it against the metadata column.

Hi @BN-12021351-0,

There is (sort of) a workaround you might want to consider. Insert a Form on the screen with the DataSource of your SP List and the Item
LookUp( SPList, ID = YourGallery.Selected.ID )

and put only an attachment control in it. When you select the attach icon in the gallery, set a Variable
UpdateContext({varAttach: true})

and make the Visible of the Form
varAttach

Add the attachment and then on the Save Icon
SubmitForm(FormName); UpdateContext({varAttach: false})

You might also want to include a Cancel Icon with
UpdateContext({varAttach: false})

If you want to upload the images to a Sharepoint Library rather than a list you can use the Flow workaround.
