' Ooh, thanks for that. ok. So if I convert my picture to png and then upload it again, it'll lose the speckles?

Or is it not that simple?


I hope so, or you could simply save the GIF file I have converted already below if you are happy with it - and upload it as your avatar.

I don't claim to be an expert in such matters, but I think the cause of the measles/speckles is to do with dithering of the colours.

Basically in computer land there are 216 colours which look like the colour you ask for on all browsers and all computer screen resolution settings. (ie they will never dither) Some colours are also reserved by your operating system.

Now if the colour in your picture is not one of these, it will try to find a close match, (dithering).  Dithering is the attempt by a computer program (eg your browser) to get as close to a colour from a mixture of other colours when the required colour is not available. 

GIF files can only handle up to 256 colours, when you work with a jpg/png file that might have millions of colours in it, it has to downsize it to a gif format, and in the conversion some colour loss has to occur.

If you can upload your file in png format it might look better (as only the gif files here appear to have the measles), or you might need to use the colour replace tool of your imaging editing program to change those speckles to a non-dithering colour.

A list of those colours and the RGB settings can be found in  http://primeshop.com/html/216colrs.htm to pick your colours that are closest.
Also check out  http://support.microsoft.com/kb/312246

hope this helps 

I've removed the dithering in the below gifs to show what they would look like

Looks like the last time I updated the iamge manipulation libraries on the server, something went a bit lop-sided.  Will try and fix it soon.

I don't know, The Minx - like your new name, by the way! My avatar has suffered badly from this problem, as you see! By the way, Suzylee, I love your avatar. Where is that photo from? Looks pretty recent.

Does anyone know why some people have been having trouble with uploading their avatars only to find white bits on the pictures?  It seems to particularly dislike the colour black!
