100 x 100! They appear to be automatically resized to 80 x 80. This is not acceptable.
Actually the 80 x 80 seems to be a restriction of this theme layout (terra incognita)... I'm trying to see if I can find where that restriction in in the voluminous amount of files for this particular layout. If the smaller size is killing you badly:
1. Go to Profile
2. Click on Layouts and Themes
3. Where you see Forum/Board click the 'change' link
4. Select any theme other than default or Terra Incognita. You will get a SMF theme that came with the program (I haven't tweaked settings in those) and your Scott avatar will look peachy at 100 x 100.
