You seem to have good progress toward a workable solution already, but
FWIW here's how I handled a similar case:
I was building a bespoke authoring system which included an image
library. There were some 2600 images in the collection when we started,
and at the rate of new additions we didn't
Tom,
Ok... I finally figured out the setting of dgNumberOfRecords and adding a
GetDataForLine command. So, the data is now loading. And, I am doing the check
in FillInData to see if the image is loaded or not. If it's not, I call
getAndCachePreview with in turn does the download of the image.

How do you do that? What property do I set, or method is used to only load the
displayed rows?
Tom's code snippet is a WONDERFUL start a

This is key, that way you only ever trigger loading of visible rows.
So I've not got much to add to Tom's method
i.e. make
notice the use of send "" in 0 milliseconds...
This ensures that the rendering of the grid does not get held up by the
download. so the download happens in the background.

This is the code from my dg column.

Tom,
Yes, assuming that is a DG in your video, that's just what I'm looking to do!

These images are loaded as the row comes into view.

Richard,
Probably not over a couple thousand. The images are square -- they need to be
resized to the DG template image size, but not scaled (H vs W).

How many images?
I once made a solution for 3,000 images, but it may not scale well above
8,000 or so depending on memory and connection speed.
