There is another depth to this question about escaping forward slashes with the s modifier. With my example the capturing becomes the problem.

$image_name =~ s/((http:\/\/.+\/)\/)/$2/g;

For this to work the typo with the addition of a second forward slash, had to be captured. Also, trying to work with just the two slashes did not work. The first slash has to be led by more than one character.
