NetBox version

v4.4.0-beta1

Feature type

Change to existing functionality

Proposed functionality

When loading any model webpage (i.e. /dcim/locations/12218/), all Image Attachments are preloaded so that they can be displayed when hovering the mouse over the filename. For large images, this can slow down page loading and waste bandwidth.
Now in 4.4.0 we have thumbnails for each image, so it would be better to pre-load those instead, since they are only used for a small popup. Clicking on the image would still load the full image

Use case

It would speed up page loading and reduce network traffic. In this example, the network console shows the image-attachments page loading about twice as fast as the location page.
