JodieRD, I responded to your other post about this same issue as well. I ran into the same problem. Not sure how to fix it directly, but I did come up with a workaround. The images on my iboxes are all 50px tall by 50px wide. One of my images sat about 20px higher than the other two images. For the image that was too tall, I went into my picture editor and added 20px of blank white (color of my website background) space at the top of the image. The final size was about 70px tall by 50px wide, with 20px of blank space that matched the background color at the top of the image. It worked well! It’s still not perfect, but it’s much much closer to what I want to see. My site is: thewelleg.com… still under construction but you should be able to see how the ibox images line up.
