Some things that are not correct.
The thumbnail sh3img271220051044398280zs5nf.jpg is a full-size image (1024x786, 478KB), resized by the brower to 200x150. The other thumbnails are ok, 200x150, but the filesize of all of them is too large. All 31 thumbnails (the 478KB "thumbnail" not included) are 1.05MB.
As a general rule, if a thumbnail of that size is larger than 7-8KB then something is wrong. All thumbnails combined shouldn´t be more than 200KB. Learn the correct use of JPG compression!
