You need to have six thumbnails for all image? It' not mandatory!
The plugin works well using different thumbnail sizes, because in this way it can always guarantee an high quality of thumbnails. But, when you know the row height you will use, you can do some semplifications.
The simplest case is when you have, for each original photo (e.g. "myimage_b.jpg"), only one thumbnail (e.g. "myimage_t.jpg").In this case is only necessary to change thesizeRangeSuffixes
option to be the same for all the sizes.
Note that the following example uses too high rows for the provided thumbnails size. In this way we can evidence the fact that no bigger thumbnails are used.
<div id="oneSizeExample" > <a href="photos/8083451788_552becfbc7_b.jpg" title="What's your destination?"> <img alt="What's your destination?" src="photos/8083451788_552becfbc7_t.jpg" /> </a> <a href="photos/7948632554_01f6ae6b6f_b.jpg" title="Just in a dream Place"> <img alt="Just in a dream Place" src="photos/7948632554_01f6ae6b6f_t.jpg" /> </a> ... </div> $('#oneSizeExample').justifiedGallery({ sizeRangeSuffixes : { lt100 : '_t', lt240 : '_t', lt320 : '_t', lt500 : '_t', lt640 : '_t', lt1024 : '_t' }, rowHeight : 250 });
