"unclepedro" wrote me he is missing an image.
In the subMerged/images folder there should be a file called 'trans.gif'.
It is a 1x1 transparent .gif image.
Since the script regularly calls upon that file and I was dumb enough to forget it, please use this temporary fix until the new version of subMerged will be ready.
1.Open the images folder of submerged.
3.Rename that copy 'trans.gif', and place in the same folder of spacer.gif.
