First of all, you must have your own Yahoo!ID, like mine email@example.com. So, you logged in and go to Yahoo!Mail. Just like this...
On the picture above, you can see the red mark on it which is showed that I already signed in and you can see the EDIT PHOTOS on the bottom of the picture.
See! That's the EDIT PHOTOS I've marked! So, click on it and....
...and all you can see is this interface right on your Yahoo!Mail main screen. Then, click on the 'upload photo' as shown above..
As you choose and uploaded your photo, you can do the editing work using the tools that have been provided as above shown. So, this is my choice! ~ that's my photo posed in my office's desk!
Ok, this is when you wish to adjust the saturation and temperature of your photo.
And this is the great features that you can have here! Like adding effects, text, stickers, frames, etc... You even can zoom your photos to view in detail.
This is when I want to add text. You can change your text's color, size, blends (if you want to multiple it or lighting it..etc..). There is also various fonts that you can have here. You don't need to install or anything, its automaticaly there! Trust me...
Ah-ha..I like this part, as I said; you can add stickers on it... A fancy sticker! Like this lipstick-sticker, you can change the color. See the tools on the right side...
Here's another... I told you, there's so many free stickers that you can choose here. But there are also some nice stickers which is not a free-use...hm
Satisfy? Save or Share your photos by clicking the yellow button right on the top of right corner of the screen. Here's some settings that you need to do. As you click the Save Photo button on the bottom, your 'Save As' window will appear as usual. Don't worry. It wont be saved in the internet.
This is the result! Easy right!
Well, there's a lot of benefits of this. Because, you're not require to install anything before using it. Just maybe a common flash player. With using this, you can also edit your photo at any computer without having to worry if they have adobe photoshop to edit your photo. Just sign in your Yahoo!ID and get started!
