This plugin is a must when dealing with front end image uploads

It lets you have image upload in the front end, so your visitors can upload images along with their form submission. It has many useful configurations, and recently added the option to name upload folder by using CF7 variables besides other very customizable parameters! say whaaat, now I can organize and manipulate all images by groups as I please B-). Can also rename, resize, etc. Saves a lot of time my workflow. I’ve been using it for about 7 months now and is pretty stable. And very very good price for the value you get of practicality and time saved. Totally recommended.
