Shoestring Marketing Graphics
Everyone knows the ultimate graphics editor is Photoshop, but at over $300 a copy it simplt is outside the budget for a lot of folks just getting started. That doesn't remove the urgency to find some way to create and edit your own graphics if you want to be successful.
If that includes you, I can highly recommend you take a look at PIXLR.COM
This is abwsolutely free with no registration required and I challenge anyone to find a better solution.
If you need help learning how to use it, do a search on YouTube for pixlr tutorials.
Have fun and show us what you create.
