Caching images offline

[rwittels]

Hi. I just need confirmation that I am doing this correctly please. I have 4 images in my app which were uploaded to the Media section and are listed under the heading Images. I would like to cache my images OnStart. I have used this code:

ClearCollect(appImages, {Images: ["Image1.png", "Image2.png", "Image3.png", "Image4.png"] })

Am I doing this correctly?

Do I need to do anything on each image within the app screens?

Consider this:

ClearCollect(

    appImages,

    {ID:1, Image: Image2},

    {ID:2, Image: Image2},

    {ID:3, Image: Image3},

    {ID:4, Image: Image4},

    {ID:5, Image: Image5})

Thank you for the reply. I am trying to use appImages.ID=1 in the image's Image property on the screen and it doesn't work. What is the correct syntax to access the image?

Yes ignore the extension.

In the image of the Gallery:

LookUp(appImages,ID=ThisItem.ID,Image)

Am assuming you have a common column like ID between your datasource for the Gallery and the Image collection.

Your can change the Name ID to and identical column

LookUp(appImages,ID=1,Image) works. If images were added as media, does adding them to a collection like this improve performance?

[eka24]

LookUp to the image is ok because the images are already in the App through a collection.
