In #6432 I replace that small Joomla! Logo at the bottom of the loginscreen with the icon-joomla font set icon. In combination with #6340 the style is the same.

Any chance of squeezing this in to the release - one of the current images is pretty broken #6491

I did get a couple of other graphics from Chiara to replace the "Support Joomla" and "Powered by Joomla" images and those are in here now too.

Last update. The last graphic I saw that's in use was the images/joomla_black.gif image (it's the default graphic for the Beez3 template). This is replaced with a .png version again from the main repo. The _green and _logo_black images were unused anywhere in the repo (as best as I can tell, probably old sample data images from 2.5) and I've just completely removed them. As we don't include these images in our update packages, this doesn't affect existing sites using those graphics; nor will they receive the updated imagery.

This leaves the graphics in the images/banners folder left to update (OSM & Joomla! Shop banners only used in sample data).

It should be nice if the image on the login screen and the Joomla! logo in the top right corner are retina proof. Now, they get blurry on high resolution screens.

To make a image retina proof, you had to resize the image to twice its view size. For example, the logo on the login screen is display with a size of: 256x53. So the retina proof file is: 512x56.
I have this resized files, and it works like expected:

(I'm sorry for the different language)

Is it possible to implement these files? I'm asking because of the different file size.
If it is possible, I will make a PR to your repo so you can merge it into this PR

Honestly, I'd rather not get into a situation where I'm trying to sort out stylesheet rules to put larger images in place. Not that I don't agree with having higher resolution images, but I'm not someone who is comfortable figuring out the CSS rules for images anywhere in a document.

In this cases I didn't change the CSS files. I'm such a mad person who likes to do that :P

So I will take a look at it tomorrow, and will search where the joomla.png and logo.png are used. With a little bit of luck there not used often, and the display size stays the same.

But I understand your thoughts. It is just a possible idea :)

After some research:
joomla.png is only used on the login screen of the isis template and logo.png is only used in the right top corner of isis. So change these two images to a new images with twice it's size doesn't affect other pages. I don't see any reason why we shouldn't change the current image to these images:

administrator/templates/isis/images/joomla.png

administrator/templates/isis/images/logo.png

Merged in the retina graphics for Isis. Any reason this cannot be merged in soon-ish?

Set to RTC based on Review.
