Why shouldn't I use `v[0-9]` within folder names?

When using v[0-9] within folder names it can sometimes cause ambiguity and lead to broken URLs on your website. The reason is that, for example, a folder named v5 (after the band, of course) can also be parsed as an attempt to "version" a resource number "5" over the base image.

To be on the safe side, you should be sure to obey one of the following:

• Avoid using "v[0-9]" within the folder name.
• Use versions to isolate the public ID from the transformation section.
