Image gallery loading efficiency creative ideas

Hi All,

Not being of a programming or formulas background, I am calling upon the group for some inspiration/guidance please.

I built an App that functions as an image library. The images are stored in a SharePoint Document Library.

Users will have the ability to filter images based on different criteria.

Currently, the gallery calls upon SP to display all images, then the user can filter what they want to see. This is a terrible slow process as the images reload each time the user returns to the main screen.

At this time, there are under 40 images and there is a noticeable, almost painful, slow loading time for the images. And this makes sense to me. There are several megabytes that need to be transfered.

I'm looking for creative ideas of how to make the library a nice experience where the user does not need to wait for a collection to build or images to transfer to the application from SharePoint.

What would be a smart why of doing this?

Thank you All :-)

Hello,

one way I use in my applications is to create a container that contains a loading GIF or just a label saying "Loading...".
I place this container above all other elements on the page.
In the Visible property of this container, I use a variable.
When I start a collection or any process that takes time, I set:

Set(varLoading, true)

And at the end of the process, I set:

Set(varLoading, false)

Example:
Set(varLoading, true); ClearCollect(colImage, SPDataBaseImage); Set(varLoading, false);

This way, the loading screen appears only while the data is being processed.

Are you loading thumbnails or the full image?

40 images shouldn't present problems if the small size is being loaded

Thanks @Ytalo Silva. I do have a default spinner that appears. This is helpful from the user perspective letting them know that the app is doing something.

@ronaldwalcott, I'm loading Large thumbnails. The resolution of the Small thumbnails is too poor for our use.

I think I'll try to create a collection at startup. When new images are loaded, that is when the collection will be refreshed for the user. Maybe like this I could have a one-time long loading time. The majority of users will not be permitted to upload new images anyway.
