Hi,

The typo was in a closing tag in each tr block. The backslash was missing.

but when I copy and paste it, all of my images disappear,

Works like a charm here. You may have to wait a little while for the images to be loaded. After all, the file server has to create downscaled preview images for all these images first.

Does it affect the LIL bot?

Yes, the bot won't find the images in the post.
