Max File Size for Gallery Images: Many of the forums have sub-forums that are special "Gallery" forums made especially for uploading pictures of your cars. The number of images you can upload per post in the Gallery forums depends on your subscriber level. This section indicates the maximum file size allowed per image you upload at the indicated subscription level. The free and Bronze levels allow each image to be a maximum of 150 kilobytes file size, with increasing file sizes allowed for higher subscription levels as shown.
