Hi All,
A reminder:
The maximum Byte-size allowed for avatars is 20 KB.
The maximum pixel size is width: 150 pixels, height: 150 pixels.
There are quite a few avatars which are within the pixel limits, but well over 20KB.
Admin has been converting some of these from PNG format to JPG format with 50% compression.
It makes a surprising difference:
in general, the same picture in JPG is less than 10% of the PNG size !
A 34KB image can reduce to 2-4 KB, presumably depending on the colours and contrasts.
If you are not sure of your avatar size, then right-click on it. In the context menu which then appears, left-click on properties. A pop-up window will tell you the size, in pixels and in Kilobytes (KB)
You are responsible for the size of your avatar. If you change your avatar please remember this.
In future, if your avatar has already been re-sized by admin and you replace it with another over-sized image, it will simply be deleted.
regards,
Bob

I assume my avatar is OK, as it is only 12.85kb, but what is interesting is that the photo I used is a jpg, but when I click on properties of the avatar it shows it is a PNG image. How did that happen?

Can someone tell me if my picture is OK, or if I should remove it in favour of something smaller?
I read this thread earlier, and took my picture off, reduced in to size to what in 'My Pictures' Properties reads as a JPG, size 7.78KB and then reposted.
I've just read Lizzie's post, and right clicked on my picture as it appears on a Rootschat page. It's now become something else, and says it's 32478 bytes.
I think I need a translator
Maggie
p.s. avatar? I might as well give up, I thought that was Amy Johnson..

Mine too. Looks like we have been modified!
Yes, but Bob states: Admin has been converting some of these from PNG format to JPG format with 50% compression.
So our avatars have gone the wrong way 
Maggie - 32478 bytes is 32.478KB. Actually, the properties of your avatar show it is 31.72KB

Oh, I see what you mean Lizzie!
Mine was definitely a JPeg when I posted it!

and mine's nearly quadrupled in size - it was reduced down to 7.78KB and a jpg. when I posted it earlier this morning! I'm going to take the picture off until I can work out how that happened, because it really is only that smaller size, I've just checked.
Lizzie, thanks for the explanation.
If Bob, Arranroots or someone can explain how that happened or where I went wrong I'll put it back, but much as I like the photo having it downloading loads of times and clogging up the site speed is unlikely to endear me to everyone else.

Seems like someone went the wrong way with yours, Maggie
I posted a new one yesterday - it was a jpg, 7.06kb and 106 x 162
It's now jpg, 2.87kb and 98 x 150
Obviously made smaller to reduce the height
I could have chopped some sky off if necessary
Maybe I'll just be a blank and save a h*ll of a lot of space with the number of postings that I've got

Thanks Gadget,
maybe the problem was mine was landscape rather than portrait, and too wide? Just like me, in fact

I've asked admin:
the avatars from Maggie and Lizzie haven't been changed.
Gadget, the RootsChat software automatically resizes the avatars (pixel wise) so that whatever is larger, height or width, gets reduced to 150 pixels and the other dimension gets reduced proportionally.
Unfortunately automatic resizing is only done on the pixel-size, not on the KB-size.

Thanks Bob, I'll still keep my picture off until I can be sure it's a smaller size - or find another picture

Thanks, Bob 
I had suspected that when I checked. I have always worked to a 100 pixel wide avatar and less than 10 kb (I think those were guidelines you mentioned ages ago). I'd not realised about the height limit!
My avatar must take up an awful lot of space though with my posts and I don't mind just being a dot if it would help
