Hi mikehende,
I can see that the 3 header pictures are 1240×675, which is the recommended size for the image sliders.
If you want to get images from iStock, look for pictures that are the same size or bigger so they fit in the slider.
Remember that bigger pictures may take longer to load, so choose a size that works and is optimized for your website.
All the best!
Yes, I am seeing the closest size to this is 1254×839, thank you very much for the help!
