I made a good one by using html5maker :
http://html5maker.com/#/After everything, I found that I can only get them in html format or swf format. Plus they got a Powered by html5maker on the bottom of the banner making it look really stupid.
I don't have Photoshop or Adobe Flash Professional, etc. installed on the computer.
How do I make a proper gif banner? Can I do the animation effects?
There are different techniques which depends on your software.
You can for example install trial version of Adobe AE and there you can make some animations which you can later on render to images sequence which you can convert later to gif.
You can also use Sony Vegas and Photoshop.
There are many ways to create animated gif.
PM me if you need a lesson. I can record some tutorials for you
Kind regards.
