EasyImg, to mention at first, is a very different kind of web service which can be very powerful under the creative hands.
It is a highly customizable web-based graphics engine that enables anyone to insert "instantly created custom images" to their websites.

How it works?
EasyImg works by sending a formatted query to the service as the source of an image. An example will describe it better:
<img src="http://images.easyimg.com/fd592fce/h-60/w-480/bw-2/r-15/bc-e0dede/fc-fcfbdc/c-fc2671/font-Tahoma/size-30/banner.png?text=WRD Test Banner" />
will return:

where:
fd592fce = is the token for my account
h-60 = height is 60px
w-480 = width is 480px
bw-2 = border width is 2px
and you can possibly guess the rest easily..
Besides the standard image properties, it is possible to use various fonts, rotate the final image, add gradients & more.
And, as it doesn’t use any JavaScript or CSS hack, it is totally compatible with any browser.
EasyImg can be set to re-create the image every time it is called or use caching for faster usage.
Also, it is not a must to host every image generated at the system. They can be downloaded as a single ZIP file anytime.
Where can I use it?
Primarily, it is a great fit to be used in websites where images must/can be customized like:
users customizing the look & feel of their accounts (you may need to create rounded corners with different colors)
usage of rotation
usage of custom fonts
no image editing software (ideal for customers who are not into webdesign but want to update the look of websites – can be integrated into CMSs)
And, it is a perfect fit for special cases like dynamic barcode generation (just use the barcode font).
EasyImg comes with different plans where a free one exists as well.
You can see how powerful it can be with the options it offers & from the samples. Or, you can play with the online canvas.
