When using the
![title|widthxheight](image-url) formatting, thumbnails are generated only when the original image is bigger than certain dimensions.
This is smart but a problem comes when you want to display a gallery in a post.
Here’s an example :
If you click on the first image to enlarge it, you can slide through the gallery using the ⇽ arrow keys ⇾.
Unfortunately, 2 of these images don’t show up in the slide show (and their thumbnail is not clickable) because their resolution is below the minimum requirements to generate thumbnails.
A solution to this would be to make images clickable as soon as a custom
|widthxheight is used, even if no thumbnail was generated.
Here’s the raw text I used for this little gallery (minus the code for the table):
![Candi Prambanan|320x180] ![San Agustin|166x180] ![Moaï|288x180] ![Bayon temple|271x180] ![San Agustin 2|240x180] : upload://wfnzm0tBLXg6BRQWnIoNfnl8HNs.jpg : upload://6troRQuaAULLkslCZau5E7mgGPj.jpg : upload://c0X0waqMVcw3W989DqQrvfZQKHe.jpg : upload://icDRdwwiwP7yGzIQNRNG9R8pLTN.jpg : upload://qhIjHkRcsr6o2eJrJtZg4TnDddv.jpg
