Photo from PowerApps Pick Picture (appres / blobmanager)

Posted on by jeanshak

Hello

I transfer a Photo from "pick Picture"-Item in PowerApps by the following order:

Patch(PhotoAppListe; Defaults(PhotoAppListe); {Title: Text(TextInput1.Text); BildSpeicher: First(ClrImg).Url; Text: Text(Now(); DateTimeFormat.LongTime24)});;

Here is PhotoAppListe a Sharepoint List; Title a Text; Bildspeicher a plain text with origin picture data.

Now I mirrow it back to the app: Gallery with the PhotoAppListe ; the picture is shown in the image-item in the gallary.

The plain text is appres://blobmanager/206d2aecba8549c88e74977663d87e9c/1
But where can I find the whole picture data for a transfer to another media;

Other Case:
If I send the data from the "PowerApps Camera" then I can see
data&colon;image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAeAAAAKACAYAAABEyKtSAAAgAElEQVR4Xpy995Nl13XfuzvNdJrUkwcggEEiwWyRAGQSzBRpycWSRD+X419pPz/r6f1iWypZJESXCQYQBEgkTgIwuad7puOrz3ft7znr7Htu99C3gJq+5 etc .....
If I cut the first 22 Bytes () and convert the data to base64
(( byte[] imageBytes = Convert.FromBase64String(base64String);))
I can receive a correct picture.

I have the same exact problem. Unfortunately I haven't figured out a solution yet.
I am starting to think that there might just not be a solution at this point...

Hi @jeanshak ,

There is a hack through Flow to solve this issue.
Have a look at this blog by John Liu.
http://johnliu.net/blog/2019/4/flowninja-hack-87-lock-microsoft-flow-powerapps-trigger-to-upload-images-to-sharepoint-with-ease

You can skip the first part of the blog where he dives into the code of diveren connectors to find the sollution. The 2nd part of the blog describeds the hack.

Basically the steps are:
Create a Flow triggered from PowerApps
Add a condition that will result in a false output (for example 1 = 2)
In the 'If Yes' branche add a Outlook - Send an Email action.
This action will never be run, so whatever you put in the To, Subject and Body fields doesn't matter.
In the Attachments Name - 1 and Attachments Content - 1 add the 'Ask in PowerApps' dynamic content parameter.
Add a SharePoint - Create File action and add the site address and folder path.
Add the generated dynamic content parameter created during step 4 in the File name and File content fields.
Make sure they match up correctly to Outlook Attachments - 1 fields.
Add the Flow to execute from within your app and make sure to provide the requested parameters (file name & file content). File name you need to generate yourself (for example GUID(). & ".jpg"). For the file content you can use the output of the Add Image control (appres://blobmanager/.... etc.).

And run!
Tried it out today. Works like a charm (allthough a little bit weird work around).

Hey,

is this still working?
I've been trying to get this function to work for 2 days now and have made countless attempts, unfortunately without success. The instructions are unfortunately all incomplete or something has changed since then? Picture 1 and 2 show my flow. Picture 3 my button in Powerapp and Picture 4 the faulty result in Sharepoint.

Thanks in advance.
BR Felix.

Hello everyone,

I found a elegant way to save a photo taken in Powerapps in Sharepoint. But the photo will be converted to a PDF. I did not find/search a solution to convert it to jpeg.

Here is how I did it:
For the Powerapps Button:
'PowerApps-Flow'.Run(AddMediaButton.FileName;JSON(UploadedImage.Image;IncludeBinaryData));

The Flow looks like this:

I hope it helps someone!

Regards
Niklas

Hello. I found this page while trying to deal with the same issue (6 years after!). I don't find a relevant answer on this page.

This is my post from yesterday: How to handle image conversion with the AddMedia control?

If ever since then you have found a solution, this is not understandable to have it work perfectly a few months ago, and then suddenly this issue appears (the apres:// url instead of the real image content).

Thanks if you or someone can help!

Gilles.
