Lengthy GIF loading

Posted on by Revl0ck97

I have multiple GIFs stored in a collection sourced from a SP site and displayed in a gallery. The problem is that some of the GIFs are kind of large and most of them take at least 2 mins to show up in the gallery.

I tried Clearcollecting it on the OnStart but when I get to the screen containing the Gallery GIFs it still takes so long to load and show up and is just showing a dark grey image in the mean time (previously it was in the OnVisible of the screen itself) but there is almost no difference in loading time. Is there any other way for me to optimize this? I would like to upload them directly but not even half of them would fit in the 200 MB media limit.

Hi @Revl0ck97

Realistically, I think the best approach is to see if it's possible to reduce the size of the source images. If half won't fit into the 200MB limit, that's an enormous amount of image data.

If the images are directly accessible by a SharePoint URL, you could try displaying them directly using the image control rather than collecting beforehand. By doing this, the browser should cache the images meaning that the app won't have to fetch them again on subsequent loads.

Hi @timl ,

I've tried directly looking up the GIF instead of a collection. I put them side by side but the performance for both were almost exactly the same. Also, whenever I would go to another screen and back to the screen with all my GIFs the image controls would go back to grey it's like reloading everything again. However, It was my bad, all the GIFs actually would fit the 200 mb limit but barely. Will try uploading them all directly (and use a collection as well as directly from Media and compare) and see if there is any improvement. If not, I will try reducing all their sizes.

Will let you know which gives the best outcome. Thanks a lot!

Hi @Revl0ck97

Thanks for the update.

>>the screen with all my GIFs

So just to clarify the above point, you have a single screen that displays all (or many) pictures at the same time? That would explain the dark gray image as this would be a significant resource overhead.

From within SharePoint, are your GIF images stored in a list in an image column? If not, this is something I would suggest because SharePoint will create thumbnails and you can display the thumbnails in 'overview' type screens to reduce the load time.

Hello @timl ,

No, the GIFs are stored in a list but in an attachment column. I'll try your suggestion on this, thanks a lot! In the meantime, I tested out the different kinds of ways to display the GIFs. I compared the collection, a direct lookup to the SP list, A direct lookup in a Dataverse image column and from Media.

As expected, the GIF from media loaded the quickest however, it isn't viable since the app's performance really took a toll after uploading all the GIFs in media. The collection and direct SP lookup loaded at the same time but also took the longest. The most viable option in my case as of now is from Dataverse. It was only a few seconds behind the media option. I had trouble at first with it when I stored it in a file data type but realized a full image data type was what worked.
