[FIX] add relative-path of source image to target-path if target is cache-folder

[rommelfreddy]

if an image exist with the same name on two different locations, the module may override the image.

so we need a function to add the relative path to the target directory.

Feel free to add unit tests

Could it be that this is actually already supported by the original cache folder itself? I might be interpreting your PR in the wrong way though. In later releases of the module, the cache folder is made configurable: https://github.com/yireo/Yireo_NextGenImages/blob/master/etc/config.xml#L21

sorry to reopen this issue. i miss-interpreted your referred code.

No this resolves not the issue.

The issue is, that if two same named images does exist in two different locations - e.g.

• /path/to/the/first/image.png
• /path/to/the/second/image.php ... the images got overridden by each other.

this will result in unexpected behaviours. So we have to add the relative path to the new directory, if it is in a different directory.

I changed my commit, cause this is not really a feature. it is more a bug fix.
