Well…as all of your images appear to be working correctly…it’s difficult to guess what may be happening.
All I can suggest to you is:
+ check the module’s parameters to make sure the thumbnail image size is what you would like.
+ make sure the original image size is LARGER than what the thumbnail settings are.
+ and for best performance, it’s always best to have an original image that can be proportionally downsized to the thumbnail. ( i.e. if you want a 50 X 100 thumbnail, then try and cut the original to be something like 100 X 200, 125 X 250, 300 x 600 etc.) At 180×90 you’re looking at a 2:1 ratio. So you would want to cut the image to be exactly twice as wide as it is tall.
Have fun! And say hello to Sally for us!
