Please ensure all images have been resized to be exactly the same size, otherwise a background colour of red will be shown.

Hi, I have the same issue with the red background, my images are the same size as the indicated in the block. They are png files. How can I make the background transparent. My sitehttp://www.kiva.com.ar/mark Thanks a lot

Unfortunately this block won't work well with transparent PNGs - otherwise the matte red background will show through. Best to use JPEG images or PNGs without transparency.

Hope this helps.

All right!, thanks for your answer. I'll use JPGs.
