Very recently I recommended a PSD with avatars to speed up the process of creating users when we are designing a system and, now, I find this useful extension that makes the implementation of images even easier. profile in Photoshop.
As seen in the images, the panel presents a sex selector and then two options to quickly include random photographs in our psd.
The extension, although it is free, offers the possibility of donating the amount that one wishes and requires uploading the email to download it.
