Patch canvas app Image directly to Dataverse 'Image Column' from Collection

Hello, all

I am in desperate help with this one... I have been trying unsuccessfully for hours now to patch an image file in my canvas app to a Dataverse 'Image Column' .... Scouring every post and hint I could, I have successfully converted the image to base64 (via the variable method)

Set(BinaryImageData,Substitute(JSON(imgDeviceOldSNImg.Image,JSONFormat.IncludeBinaryData),"""",""));

And have put that resulting variable into a new image file and it is displayed as expected:

But no matter what I do, it will not patch into my Dataverse table. It shows no error, but that column will not populate with anything. I have tried directly patching that image file with the ForAll statement and the following code for the image column:

 cr369_olddeviceserialnumberphoto: {Value: imgDeviceOldBase64.Image, Full: imgDeviceOldBase64.Image},

Again, no errors but nothing will show up in Dataverse, I'm wondering if I need to shorten the Base64 code as I have read in some posts...

HELP ME PLEASE !! My app goes live tomorrow, and I can't store the images in Dataverse! )

Thank you in advance for any urgent help you can provide.

Hi @LeeB_CDN ,

Could you please share more details about your scenario? How will users upload images to the Power App?

If you have an Add Picture Control in the App then you could simply use the ImageControl.Image. Below is a blog about the common solution of update images to image column of Dataverse:

Below is my simple sample app:

Hope this helps.

Hi @v-jefferni ,

Thanks for your reply, I managed to figure this out by using the multiline text column workaround for Dataverse however, I am still only getting thumbnail image sizes. Unfortunately, I have to use the camera control (as opposed to a picture control) within my Power App due to privacy concerns with personal devices with company data (images) as the camera control only uses the local cache to take and store images...

Any ideas on how to specify full resolution base64 in with a multiline text column in Datatverse?

Thanks for your reply!
