Random Image/GIF Generator

Posted on by Community Power Pla... Microsoft Employee

Hi everyone,

I would like to have a randomly generated GIF in my app.

I would store the GIFs in a SharePoint list (or document library? not sure here).

Each GIF (there are 50) would have a number between 1 and 10 AND also have a "Day Tag" i.e. Monday, Tuesday, Wednesday, etc.

Once the users successfully fill out a form, they are redirected to another page to see the GIF and a global variable is Set to a random number between 1 and 10.

I would like PowerApps to look at my lookup list and get me a random picture/GIF depending on the random number generated AND the corresponding day of the week when the user fills out the form.

For example, I fill out the form on a Friday.

Once I successfully submit, a global variable is setup to a random number (let's say 7 in that case).

PowerApps would do a lookup in my SharePoint list for see the GIF associated to the number 7 in the RandomNumberColumn and Friday in the DayColumn.

I need help on

1. The formula of the image

2. The global variable to randomize the number

3. Whether I should use a SharePoint List or a Document Library

Thank you very much!

HI,

Try this and if you need further help will send my contact

I need help on
1. The formula of the image
- Use a list in SharePoint, Use the Lookup Function to get the images, I would use the ID in SharePoint to lookup and set the record, then have it fill the Image control form there.
2. The global variable to randomize the number
-Use the Rand() Function also in PowerApps
3. Whether I should use a SharePoint List or a Document Library
-I would use a list and put the Gif in the attachment of each list item.

Hi @Anonymous ,

1. The formula of the image

LookUp('Library Name', RandomNumberColumn = varRandNum && DayColumn = LookUp(colWeekday, ID= Weekday(Now())).Day)

App.OnStart: ClearCollect(colWeekday, {ID:1, Day: "Sunday"},{ID:2, Day: "Monday"},{ID:3, Day: "Tuesday"},...)

2. The global variable to randomize the number

Set(varRandNum,Round(Rand(),1)*10)

3. Whether I should use a SharePoint List or a Document Library

Document Library!!

I think the image formula is missing the "result".
I'm tried to add the GIF in a document library under the title column, under an image column, under a hyperlink column but nothing is working.

Hi @Anonymous ,

The GIF must be uploaded as the file. The Result of the lookup formula is:

LookUp('Library Name', RandomNumberColumn = varRandNum && DayColumn = LookUp(colWeekday, ID= Weekday(Now())).Day).'Link to item'

Hope this helps
