I am not sure that how many kb matters to most people. Even a gif image, which is constructed of multiple images, is unlikely to exceed 100kb if it fits the size constraints of 100×100 pixels, and there is no issue with posting an image of 100kb or less on this site that I am aware of.For those members that aren't aware, an avatar is simply an image placed by your name. You can upload your own image to this site and use that, or you can link to an image hosted on another site if you'd prefer. You have the option to do this by clicking on the 'profile' button at the top of the page, and then clicking on 'forum profile information' on the left of the page.Your avatar can be any image file, including animated .gif files, so long as it fits the size constraints of 100x100kb or less. If you use a larger image, it will still work, but will automatically be resized by the system.There are no constraints on how many kb the file is.
