The image loading times are determined by the file sizes. I think the file sizes of the images in the Plant Files are much larger than they need to be. I looked at a zinnia image whose physical size was 800 x 1066 pixels with a file size of over a megabyte (1,176,000 bytes to be exact).

It could just as easily have been one tenth that size and still be a good looking 800 x 1066 pixel image. It is primarily a matter of the JPEG quality setting. The zinnia picture attached here is about 100 KB (103,918 bytes to be exact), and yet it is also 800 x 1066 pixels in size. The difference is primarily just JPEG quality. The JPEG I have attached here is much more highly compressed, so it has a much smaller file size, and can load faster. I believe the file size, and not the pixel size, is what governs loading speed. The file sizes of the pictures in the Plant Files could probably be reduced to 10% of what they occupy now without reducing their pixel sizes, which would make them load 10 times faster.
