Thank you for reaching out about your campaigns! The screenshots you have provided definitely help us to understand what you’re experience. You are correct, Facebook does not allow images less than 200 x 200px. However both of the images you’ve selected appear to have been uploaded at a size smaller than this. The image selected for "Update 4-1” is showing in your library as 339 x 149 while the image for "Update 3-31" is 441 × 114. I would recommend resizing your images outside of Constant Contact or even through our image editor and re-uploading these new images.
