We thought you might like to see this post from last year again...just in case you missed it. Picnik is a great place to start (they have free and paid accounts), but if you're a pro you'll know how to use Photoshop and PS Elements to create your button.
Making a sidebar button is very similar to making a banner when you use Picnik. (You may also use Photoshop, Elements or another image editing software).
Here are some simple instructions to get you started:
Log in to your free Picnik account.
Upload your choice of photo or image from the web or your computer.
First, you will want to size the photo or image to that of a button. We chose 150x150 (pixels), but you can chose many sizes (125x125, 200x100, 175x150 etc.). In the Edit tab, click on Resize. You will see the boxes to add your button size to.
Next, click Create, then Frames. We like Drop Shadow the best...but you can choose any frame style you like. Make sure and click Transparent Background when you use Drop Shadow.
(If you don't want a frame you can skip this step).
Now you're ready to add Text. Click on Text and type in what you would like your button to say. Shrink it to fit onto your button and change colors as you require.
Next step is Effects...this is the fun part! You can really change the look of your button by using these...try Cross Process, Lomo-ish, Duotone and Film Grain to name a few!
See the box of four images at the top of this post.
When you feel happy with the look, click Save & Share. Enter a name for your button in File Name. Make sure the dimensions are what you intended (such as 150x150). Change the .jpg format to .png format. Then click Save. You will be prompted to save the button to your computer. It's easiest to save to your Desktop so you can find things more easily.
You will now be able to place your button .png in your sidebar - to create HTML code and a code box click HERE for a tutorial.
