SharePoint Images showing on Iphone

I know there are a lot of posts on this already, my difficulty is some of the posts pre date recent updates and I am trying to find out if now (feb 2020) you can display photos on mobile devices when the image is created by supplying the image parameter with s SharePoint url?

 

Is this now possible. I have managed to send the images up to SharePoint where Ican view them their and they also show on PowerApps desktop/studio but when I publish to iphone the images are blank.

 

Help please?

Re: SharePoint Images showing on Iphone

Hi @CliveMM ,

Firstly the field in SharePoint I have found has to be called Thumbnail or it will not work. Sorry for my lack of clarity (now I read my post, this was not obvious), the Thumbnail field needs to be in the Image Library, not the SharePoint list.

To display the picture in a gallery image control, the Image property simply needs to be ThisItem.'{Thumbnail}'.Large (not the SharePoint URL you have, which should work on PCs, but not on mobile devices due to the way they access SharePoint anonymously}.

If you base the gallery on a Collection, it displays much faster on mobile devices. As you are normally only collecting the photos associated with the item, the collecting is generally very quick.

I have put the questions from your Word document below and will try to answer them as best I can.

I have two thumbnail fields set up a share point list called T1 & T2 set up like this, however I don’t know what to do to associate the field T1 with Image_1_1.jpg and T2 with the other image. 

See note above regarding the field location.

I think this is the missing link, you mentioned a calculated field and I an unsure what this means. So the field contents are blank.I want the image displayed here in an edit screen, whose data source is the same list with the T1 / T2 fields. The example below works on the PA desktop studio but images are blank when its run on am iPhone. I am hoping if I can get the t1/t2 fields populated correctly, I can just change the image property show here to the appropriate T field name.

Firstly, the Calculated field I was referring to was Thumbnail - like any calculated field, the value is created when the image is filed in the Library. For the display, a little more work, but all easily done. One option is to simply display them in a gallery (there are only two of them) and make it look like part of the form. You can get a little trickier if you want the pictures to scroll with the rest of the form.

  • Create a custom card the at least the size of two pictures.
  • Size the gallery and element height including the template size to fit in this.
  • Turn off the gallery scroll bar
  • Paste it into the card.

The screenshot below is actually two signatures, but they are JPGs and in two galleries (Collected) on two custom cards and works fine on iPhones/iPads.

Please let me know how you go.

Re: SharePoint Images showing on Iphone

Hi @CliveMM ,

You can do this with the following:-

  • The library has to be a Document Library - not a old type Photo Library
  • Create a column called Thumbnail and format it as Hyperlink or Picture > Picture
  • On a Filtered gallery either directly on the list or on a Collection of the list (collections are much quicker to display, particularly on mobile devices), insert an image control with the Image property ThisItem.'{Thumbnail}'.Large.

  • Result (Horizontal Gallery) is below (boring photos of power poles) and works well on iPads.

  • You can also expand to full screen (another screen) – Image is PhotoList.Selected.'{Thumbnail}'.Large (still fairly good quality  on the device if collected)

Re: SharePoint Images showing on Iphone

Hi @CliveMM ,

Actually, it is an known issue with images stored in SP Library -- Pictures that need authentication on SharePoint are not supported yet in PowerApps Mobile App currently.

 

As an fixed solution, I think the '{Thumbnail}' property could achieve your needs. On your side, please add a Gallery control in your app, set the Items property to your SP Library. Within the Gallery, set the Image property of the Image control to following:

ThisItem.'{Thumbnail}'.Large

or

ThisItem.'Thumbnail ({Thumbnail})'.Large

 

In addition, please also check and see if the following solutions would help in your scenario:

Please take a try with above solution, check if the issue is solved.

Re: SharePoint Images showing on Iphone

Hi there, I have set up the thumbnail columns, and also set the folder to receive the images set up as a Document Library, and images are going in there when the flow I use (which I dont totally understand yet) see attachment runs, but nothing is going into the thumbnail column with this flow, there is a missing link here some where, if you can help me find it I will be most grateful.

Re: SharePoint Images showing on Iphone

Hi @CliveMM ,

The solution I posted has no relevance to flows or how the photos get into the gallery. The Thumbnail is a “calculated” column in SharePoint and simply needs the picture filed by whatever process used.

Did you get the images displaying from the Library into the PowerApps image field?
