I'm having some difficulties with galleries and their full image displays.
From all the browsers, only in Opera the galleries seem to behave as intended.
In IE 8 the arrows for next and previous images don't show and thus don't work.
Chrome seems to get the height of the picture correctly, but doesn't give it any width (but a piece of navigational arrow can be seen on a narrow strip of the picture, and navigation - at least in one way - is functional).
And Firefox 4 gets the first picture correctly and the arrows work, but it then adjusts the width and height of frames with a one picture delay.
If first image measures 1024x768, second picture measures 640x480 and third measures 800x600, and if I cycle through them via display next arrow, the white frames would be sized like this:
first frame would fit around the image as intended, the second frame would still have 1024x768 dimensions, but the image inside would be 640x480, and the third frame would be squeezed to 640x480, cropping the 800x600 image placed inside it.
(And if I were then to go back through the gallery with previous arrow, the second frame would be 800x600 pixels with 640x480 picture in it, and first frame would crop the 1024x768 picture to 640x480).
I can't remember encountering this in Firefox 3.6, and I'll update this when i try it on XP versions (I'm on win7 64 at the moment).
