Option to preserve images names.
- better image SEO*
- images also used by other extensions (easier to find and reuse)
* alt text, file size, file name
Regarding to security, images could be partialy rename (this option exist in JCE Editor : images could be randomly renamed, but only at the beginning and/or end of the name). Those who care about images names are happy, and others take advantage of the simplicity and security of Droppics.
This function could be coupled with the ability to use images already present on the server (like old galleries that must be convert to Droppics ones without any reupload).
