Posted on by Community Power Pla... Microsoft Employee

I have been trying to display 1 of the 6 images randomly whenever someone opens the app. I tried to make a collection of all the images and use shuffle for randomization. Although it does not give any error but it doesn't show the image as well although my function is producing image output by using ".url" property. Looking for possible reasons or any alternate ideas.

Hi @Anonymous ,
One other possibility is to import the images into the media (View > Media > Images > Browse) and they will be named as per the original file. At App OnStart, you could have
Set( vRN, Round( Rand() * 10, 0 ) )
which generates a random number between 0 and 9 - you can duplicate four of the images if you have no more.
Put a Image control at the back of the screen with the Image property
Switch( vRN, 0, ImageName1, 1, ImageName2, 2, ImageName3, 3, ImageName4, 4, ImageName5, 5, ImageName6, 6, ImageName7, 7, ImageName8, 8, ImageName9, 9, ImageName10 )
and you will have one of 10 random images displayed.

I didn't even know there was a function called Shuffle(), but now I do 🙂

I got this to work for my setup by re-collecting the collection using the Shuffle function. What I did was (I have a SP Library with images):

Button1.OnSelect = ClearCollect(colImages, mySPList) // this gets my original collection of images

Button2.OnSelect = ClearCollect(colImages, Shuffle(colImages)) // this shuffles and re-creates the above collection.

You could just work the above code / process into your OnVisible / App OnStart?

EDIT: Whoops sorry @WarrenBelz , stepped away from the laptop when halfway through responding then came back to finish off and you've already responded 🙂

No problems @Anonymous - I did the same to someone else this morning. (and had not heard of Shuffle either)
My main response focus was on the URL not working and suggesting the images be imported into the app Media. I do this on our training app where each subject has a different background. The Random was an extra.

Thanks @WarrenBelz and @Anonymous for your replies. I tried Warren's approach for now and it worked and doing so i figured out the problem with my approach as well. So since i was trying to make my collection earlier on app start therefore it wasn't showing me the desired results on power studio. Even when i used Warren's method that too wasn't showing results on app start property. But when i use a button to make the collection an then do it using either my or Warren's method it starts working on app studio as well. so i guess now i will have to implement it on app start an then trust the app to work just fine once i publish the app. That's my observation for now.
