IE 10 & PNG Files As Background Image - image

We have a sprite of many icons which is 10564px x 80px. The icons are arranged horizontally.
In every other browser except IE10 the icons/images show up when being used as background images for tags with specific CSS to apply the relevant position.
When viewed in IE10 they do not show up at all and actually when you try to view the png file directly from the URL in IE10 it doesn't show either.
Any ideas?

After extensive testing, it turns out it's a limitation on the width of the PNG canvas and IE10.
PNG images would work and can be viewed right up until 8000px wide but no more than that, after that they just don't render.
After more testing it's related to whether or not they are transparent. PNGs with transparency just don't show at all whereas images without transparency show as a black block (canvas).
Whether or not MS will fix this remains to be seen... we live in hope!
The fix for us is to reduce the width of our sprite to 8000px and have two or more rows of icons/images well spaced out.

The fixes is only to separate the each individual image as single with minimum size, which will be less than 8000px wide;

Alternative to mix-blend-mode: multiply in Internet Explorer

On my site I have several hundred images in jpg format, with a white background area (in the image itself). This has worked fine as the html/body background was also white. Images appeared to be transparent that way.
Now, I am about to change the site theme and these same images will now have a light grey html/body background color. I have tried to use the css rule mix-blend-mode: multiply; to make the white areas in the images transparent. This works fine in Chrome and Firefox, but not in Internet Explorer (11).
Any suggestions on how to work around this? Just to be clear, it's not the image overall opacity I want to fix, it's only the white area in the jpg images that I want to make transparent.
If no solution is possible I will have to change the format to png or gif with transparency. That would take days to accomplish...

Why is Firefox displaying svg images wrong?

I encountered a weird Firefox's behaviour. It renders SVG images cutting parts of them or not displaying them at all, but only certain of images, not all of them. Chrome and IE are displaying them properly. Here is a link to the website I put said images on:
funjo.pl
Images which are not being displayed properly are logo in top menu bar and big blue logo with transparency on the big very top banner. The funny thing is that two icons a bit down on the same page (three rolls and woman's legs), which are also SVGs are being displayed properly. Could someone please tell me what's going on? I suppose there is something wrong with SVG image code itself but I can't detect what exactly.
I'm not pasting whole images' code beacuse it's too much of it. You can download these images from http://funjo.pl/media/2016/06/logo.svg and http://funjo.pl/media/2016/06/logo2.svg.
PS: If you really want me very badly to paste the whole code let me know.
PS2: I created all of SVGs on the website using Corel X7, if this information helps in anything.
PS3: I'm using the newest FF v 46.0.1.
Actually I've found a solution myself, it helped perfectly but required few more steps after exporting SVG in Corel X7 (as I mentioned in my post above there were two images, one of them with transparency). So here are the steps I made to make it being displayed properly in FF (a bit trial and error procedure but works):
I exported both SVGs again removing transparency from the one which was originally transparent, so no transparency at all in both SVG images. The one used as logo in menu bar contained all the elements grouped (logo and text were both separate but grouped), I ungrouped those elements and made them as one.
I removed height and width attributes from both SVGs.
I added preserveAspectRatio="none" attribute so I could manage width and height of the image separately, just like raster images (this CSS Tricks article helps a lot with understanting the whole resizing process).
I used SVG Optimiser tool to remove all the unnecessary bits from my images and to slim them down a little.
I downloaded optimised SVGs from above mentioned tool's website, uploaded them to my website's FTP.
I added height:(some)px and width:auto attributes in CSS
I added transparency for the one which was supposed to be transparent via CSS - opacity:0.7 in this case.
Refreshed the website and voilĂ , it works like a charm. Hope it will help someone with the similar problem as mine.
EDIT
Here are images to compare, working one and not working one.
PS: After some more trials and errors I found out that changing standard text to curves in Corel X7 makes FF render the SVG image properly without above steps, but it doesn't change the fact that it worked properly in Chrome and IE anyway even if the text wasn't changed to curves before export. Plus FF didn't display SVG exported with transparency at all and Chrome and IE did.
You could open a working and failing SVG file into your text editor and find differences in the generated HTML.
I guess there is a difference the way you save it or how the vectors and layers are put. Maybe some transparent layer on top off the image renders strange?
Applying a width of 300px or above gave me the correct results as in chrome and IE.
So just give a width as below and probably you can adjust the width as per your requirement.
Hope it helps.
<img style="width: 300px;" src="http://funjo.pl/media/2016/06/logo.svg" alt="Funjo">
I solved it by removing commas , by spaces

fix for blurry images on browsers used by a mac retina

I am making a game sorta like cookie clicker, and I want the images to look 8 bit. I use a macbook pro retina, which has four pixels for every one pixel on a normal screen. On Chrome and Safari, instead of each pixel being represented by 2x2 pixels, I get a bunch of blurry blobs... I don't have this problem on FireFox. There's this one website called pixeljoint.com that is made for pixel art, and I don't have the blurry problem there. Whenever I open one of the images from PixelJoint in a new tab, the image goes back to blurry. I heard that the problem is that the images are scaled before they are displayed on chrome and safari, but I'm not too sure.
Here are two screenshots to show what I'm talking about:
I would also like to point out that the images are normal .gif files.
I am aware that you can convert a gif file to an svg with this link
and an svg file looks fine on retina.
All I want to know is how PixelJoint makes the pixels look so smooth.
I figured it out, you need to use CSS!
<style>
img {image-rendering: optimizeSpeed;image-rendering: -moz-crisp-edges;image-rendering: -webkit-optimize-contrast;image-rendering: optimize-contrast;image-rendering: pixelated; -ms-interpolation-mode: nearest-neighbor; }
</style>
I found this in the source code, so I guess this is how PixelJoint does it.

Firefox Addon manager blurry icons

I created an extension for Firefox and made a simple icon for it.
But when I tested it in the Addon manager the icon appeared blurry despite my source image was fine.
I started to experiment with different sizes and shapes of the icon.
Figured out that the icon container is 48x48 pixels and the default addon icon is 32x32.
But for any experiments the result was the same.
So I created a simple rectangle icon drawing it by pixels so it shouldn't blur anyway:
But the result blurred again:
There is some sub-pixels around the rectangle though the border should be crisp...
In pixels view:
Also I found the default extension icon (a puzzle piece) and in pixels it looks perfect but in the manager the borders are blurred a little though it's not obvious at first glance.
Are you sure this is not happening when you save the image? I don't know what app you are using, but many photo apps try to compress jpm images when you save them by default. Check this first.
Usually this does not happen with png images, so you could try using a png image instead as well.
It was silly enough... The broblem was the page scale not 100% on the Addons page. Pressed Ctrl+0 and all restored.
It happens sometimes on other web pages when I zoom in/out the view and images lose their sharpness.

Chrome resizes svg images

I have an img menu with svg images that changes the svg image with a identical image with a different color when you push in menu. When I test it with Chrome it works fine until you visit one link the second time, that chrome resize it to a smaller image.
I've made a lot of tests... I've tested :visited css, user agent css, and many another properties and it seems to be all ok. When you changes some css property in developer tools it changes automagically to correct size.
My last test was to change the width from 135px to 134px (don't ask why) and it works in 1680x1050 screen but not in 1920x1200 screen (???????). Is it an aspect ratio problem?
I'm getting crazy!!
I'm using angularjs to make the black image to red image change, but I think this is not the problem (it does a src replacement)
You can see it in the webpage http://silviaperezcruz.com.
I'll apreciate any kind of help.
PD: Sorry for my bad english
I couldn't see an obvious reason why it is doing it,. But if I had to guess, I would cast a suspicious eye on respond.js first. Does it still do it if you remove that?
