I am trying to make the fullsize image to link to the next image in the album but it doesn't seem to work. I can see that it is linking to the next image but it isn't showing the current full size image.

This is the code I used
" title=""

If you want to use the full image instead of the sized one you need to change your theme's image.php to use it instead.

By default there is no next/prev for full images itself because it is not really displayed on a theme page. It would be possible to create a custom theme page for that to mimic the image.php behaviour with it.

So what exactly are you doing and want to achieve where?

I am trying to make a comic site so I needed to make the full size image to be linked to next image

My else statement isn't working it just shows me a blank page

What did I do wrong?

Yes, look closely at the else statement and the enclosing `` tags.... There is a html error as well.
