I found the javascript to increase the size of text but it does not increase the size of .gif images. Is there another piece of code to do this?

I don't understand why you'd need a javascript to increase (or decrease) text or image sizes.
Look into responsive design and responsive images.

Most (all?) browsers today have a zoom function for both text and images.

There is no zoom for safari on the ipad, believe it or not. So I have do it with javascript buttons as bookmarklets which is javascript in a bookmark on the bar. Works fine for the text, but I need it to increase the size of graphics too.

Here's the code.

Of course there is, see http://www.apple.com/osx/what-is/gestures.html . Though that's about Mac OS Mountain Lion, gestures work on the iPad too, as you don't even have a mouse there.

Some websites (believe it or not, and I wouldn't recommend it) disable magnification on an ipad, but normally of course you can pinch or ?? (what do you call the opposite of pinch) to change the zoom level of any webpage on an iOS device.


This tag will disable the ability to zoom a webpage due to the last parameter.
