photo editing software or website

i use jasc paint shop photo editor which i think was downloaded free from the net

When using picassa save your imge on the drive other than C, then open it with picassa for editing it will make a copy of it on C drive and then edit it. By doing this your original copy on other drive remains as it is.

I use Paint.Net. I used Photoshop for the longest time and hope to go back when my computer decides to stop turning it down. :( But for now Paint.Net is a really good option. http://getpaint.net

There are plenty of free editors, some very powerful: The Gimp is a top pick; version 6 of PhotoPlus from Serif is free (they want you to buy Version X3) and will do all you want and more. Unfortunately, anything that can be added in a digital photo editor can be removed with one, too, so it really isn't going to help to put a visible watermark or copyright mark on your pics. Still if you like this approach, there are also program that will add a visual watermark to images, and one free one is available from http://picmarkr.com/ Another option is to add an invisible watermark. You can get a free one from http://www.adptools.com/signmyimage/index.html and if you register, you get 12 months during which they will notify you is your photos are published on the web (their spiders trawl the Internet the same way as search engines do). Reistration costs $US9.90. One last thing: Picassa does not edit your originals: it saves them to a new directory called Original (or something similar) which does not display in Picassa, but will show up in searches, Explorer etc.

you could use the copies to edit with picassa if the software could works,if you also trying to find something can do cropping,color transformations and other effects,you could try to use Photo shop,don't know if you could use it for free but I could use it for free here

maybe you should try to use the software photoshop for photo editing. Using that, may provide you with your necessary requirements.
