You can see how it works by watching this short video:
The generated buttons are typically embedded on a webpage, but they can also be used in other kinds of digital documents, like emails or Word files for instance.
Da Button Factory is useful to emphasize your calls to action (“Purchase”, “Sign up”, etc.) by making them visually appealing.
The exact procedure depends of your website CMS. There is a video showing how to do it on WordPress.
The generic idea is to add the button image on your webpage (download the button from Da Button Factory and upload it to your site), then to follow your CMS usual way to add a link, only selecting the image and not some text as the link “caption”.
Da Button Factory cannot automatically make a clickable button image. The best it could do to bind a button image and a link target is to output some raw HTML code, but going so technical is not needed. Using the graphical interface of your CMS to add an image and “linkify” it is easier.
The buttons you create on Da Button Factory are all yours. You are free to use them for any purpose, including commercial ones, without restriction.
If you embed them on a website or app, mentioning you used Da Button Factory is appreciated but not mandatory.
You cannot with Da Button Factory, but you can with ImageFu.com button maker.
There normally isn’t one in practice. Let us explain.
All digital images are actually rectangular. However, some image formats supports transparent colors, so an image can appear as being in another shape, if the space being the shape and the actual rectangular boundaries of the image is filled with a fully transparent color. This is what Da Button Factory does when it generates a rounded button. But:
So if you select “jpg” as the image filetype, and if your button is round(ed), the space between the button shape and the boundaries of the image has to be filled with a plain color instead: here, white. Use PNG as the image format (it’s the default), as it supports transparency; that way your button will look good no matter what the underlying document color is.
For instance, Windows 7 photo viewer always show images on a white background. So it can appear that a button is intrinsically surrounded by white, while it is just the way this image viewer program display it (others may display the same image differently).
There will be no problem in practice when you embed the button (assuming it is a PNG or GIF), for example in a website or Word document, even if their background is non-white. Look:
See, it’s alright!
